The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.

I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.

This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]

Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

xhci: Bug fixes, now with more tags!

Hi Greg,

Here's five bug fixes for 3.12.

The three patches are marked for stable.  Two fix NULL pointer dereferences.
The third marked for stable suppresses some serious log spam from unnecessary
xHCI driver warnings, whenever an isochronous short packet happens on an xHCI
1.0 host.

The other two patches fix build warnings.

Sarah Sharp

When we made all inode updates transactional, we no longer needed
the log recovery detection for inodes being newer on disk than the
transaction being replayed - it was redundant as replay of the log
would always result in the latest version of the inode would be on
disk. It was redundant, but left in place because it wasn't
considered to be a problem.

However, with the new "don't read inodes on create" optimisation,
flushiter has come back to bite us. Essentially, the optimisation
made always initialises flushiter to zero in the create transaction,
and so if we then crash and run recovery and the inode already on
disk has a non-zero flushiter it will skip recovery of that inode.
As a result, log recovery does the wrong thing and we end up with a
corrupt filesystem.

Because we have to support old kernel to new kernel upgrades, we
can't just get rid of the flushiter support in log recovery as we
might be upgrading from a kernel that doesn't have fully transactional
inode updates.  Unfortunately, for v4 superblocks there is no way to
guarantee that log recovery knows about this fact.

We cannot add a new inode format flag to say it's a "special inode
create" because it won't be understood by older kernels and so
recovery could do the wrong thing on downgrade. We cannot specially
detect the combination of zero mode/non-zero flushiter on disk to
non-zero mode, zero flushiter in the log item during recovery
because wrapping of the flushiter can result in false detection.

Hence that makes this "don't use flushiter" optimisation limited to
a disk format that guarantees that we don't need it. And that means
the only fix here is to limit the "no read IO on create"
optimisation to version 5 superblocks....

Xhci controllers with hci_version > 0.96 gives spurious success
events on short packet completion. During webcam capture the
"ERROR Transfer event TRB DMA ptr not part of current TD" was observed.
The same application works fine with synopsis controllers hci_version 0.96.
The same issue is seen with Intel Pantherpoint xhci controller. So enabling
this quirk in xhci_gen_setup if controller verion is greater than 0.96.
For xhci-pci move the quirk to much generic place xhci_gen_setup.

Note from Sarah:

The xHCI 1.0 spec changed how hardware handles short packets.  The HW
will notify SW of the TRB where the short packet occurred, and it will
also give a successful status for the last TRB in a TD (the one with the
IOC flag set).  On the second successful status, that warning will be
triggered in the driver.

Software is now supposed to not assume the TD is not completed until it
gets that last successful status.  That means we have a slight race
condition, although it should have little practical impact.  This patch
papers over that issue.

It's on my long-term to-do list to fix this race condition, but it is a
much more involved patch that will probably be too big for stable.  This
patch is needed for stable to avoid serious log spam.

This patch should be backported to kernels as old as 3.0, that
contain the commit ad808333 "Intel xhci:
Ignore spurious successful event."

The patch will have to be modified for kernels older than 3.2, since
that kernel added the xhci_gen_setup function for xhci platform devices.
The correct conflict resolution for kernels older than 3.2 is to set
XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts.

drivers/usb/host/xhci.c:3901:12: warning: 'xhci_change_max_exit_latency' defined but not used [-Wunused-function]

These functions are not always used, and since they're marked static
they will produce build warnings:
- xhci_msix_sync_irqs is only used with CONFIG_PCI.
- xhci_change_max_exit_latency is a little more complicated with

When the host controller fails to respond to an Enable Slot command, and
the host fails to respond to the register write to abort the command
ring, the xHCI driver will assume the host is dead, and call
usb_hc_died().

The USB device's slot_id is still set to zero, and the pointer stored at
xhci->devs[0] will always be NULL.  The call to xhci_check_args in
xhci_free_dev should have caught the NULL virt_dev pointer.

However, xhci_free_dev is designed to free the xhci_virt_device
structures, even if the host is dead, so that we don't leak kernel
memory.  xhci_free_dev checks the return value from the generic
xhci_check_args function.  If the return value is -ENODEV, it carries on
trying to free the virtual device.

The issue is that xhci_check_args looks at the host controller state
before it looks at the xhci_virt_device pointer.  It will return -ENIVAL
because the host is dead, and xhci_free_dev will ignore the return
value, and happily dereference the NULL xhci_virt_device pointer.

The fix is to make sure that xhci_check_args checks the xhci_virt_device
pointer before it checks the host state.

See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for
further details.  This patch doesn't solve the underlying issue, but
will ensure we don't see any more NULL pointer dereferences because of
the issue.

This patch should be backported to kernels as old as 3.1, that
contain the commit 7bd89b40 "xhci: Don't
submit commands or URBs to halted hosts."

If a device in a RAID4/5/6 is being replaced while another is being
recovered, then the writes to the replacement device currently don't
happen, resulting in corruption when the replacement completes and the
new drive takes over.

This is because the replacement writes are only triggered when
's.replacing' is set and not when the similar 's.sync' is set (which
is the case during resync and recovery - it means all devices need to
be read).

So schedule those writes when s.replacing is set as well.

In this case we cannot use "STRIPE_INSYNC" to record that the
replacement has happened as that is needed for recording that any
parity calculation is complete.  So introduce STRIPE_REPLACED to
record if the replacement has happened.

For safety we should also check that STRIPE_COMPUTE_RUN is not set.
This has a similar effect to the "s.locked == 0" test.  The latter
ensure that now IO has been flagged but not started.  The former
checks if any parity calculation has been flagged by not started.
We must wait for both of these to complete before triggering the
'replace'.

Add a similar test to the subsequent check for "are we finished yet".
This possibly isn't needed (is subsumed in the STRIPE_INSYNC test),
but it makes it more obvious that the REPLACE will happen before we
think we are finished.

Finally if a NeedReplace device is not UPTODATE then that is an
error.  We really must trigger a warning.

This bug was introduced in commit 9a3e1101
(md/raid5:  detect and handle replacements during recovery.)
which introduced replacement for raid5.
That was in 3.3-rc3, so any stable kernel since then would benefit
from this fix.

We always need to be careful when calling generic_make_request, as it
can start a chain of events which might free something that we are

Here is one place I wasn't careful enough.  If the wbio2 is not in
use, then it might get freed at the first generic_make_request call.
So perform all necessary tests first.

Kernel command line: console=uart,mmio,0x90000000,115200
Early serial console at MMIO 0x90000000 (options '11520')

  still a few corner cases that didn't work properly, for example in
  relation to hotplug and devices without explicit error handlers.  We
  had some patches but they weren't quite good enough yet so I left them
  off the 3.11 merge window.

  Gavin since then fixed it all up, we ran quite a few rounds of testing
  and it seems fairly solid (at least probably more than it has ever
  been).  This should probably have made -rc1 but both Gavin and I took
  some vacation so it had to wait for -rc2.

  The rest is more bug fixes, mostly to new features recently added, for
  example, we missed the cpu table entry for one of the two models of P8
  (we didn't realize they had different PVR [Processor Version Register]
  values), some module CRC issues, etc..."

Pull crypto fixes from Herbert Xu:
 "This push fixes a memory corruption issue in caam, as well as
  reverting the new optimised crct10dif implementation as it breaks boot
  on initrd systems.

  Hopefully crct10dif will be reinstated once the supporting code is
  added so that it doesn't break boot"

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  Revert "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework"
  crypto: caam - Fixed the memory out of bound overwrite issue

This patch updates the list of maintainers for the staging/comedi
driver.

The usage of strict_strtol() is not preferred, because
strict_strtol() is obsolete. Thus, kstrtos32() should be
used in order to convert a string to s32. Also, error handling
is added to get rid of a __must_check warning.

This fixes a memory corruption bug as well.

imx6q contains one Synopsys AHCI SATA controller, But it can't share
ahci_platform driver with other controllers because there are some
misalignments of the generic AHCI controller - the bits definitions of
the HBA registers, the Vendor Specific registers, the AHCI PHY clock
and the AHCI signals adjustment window(GPR13 register).

 - CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
   should be configured to be '1'

 - bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL
   should be set to be '1'.(default 0)

 - One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
   configured regarding to the frequency of AHB bus clock.

 - Configurations of the AHCI PHY clock, and the signal parameters of
   the GPR13

Setup its own ahci sata driver, contained the imx6q specific
initialized codes, re-use the generic ahci_platform driver, and keep
the generic ahci_platform driver clean as much as possible.
