imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which
leaves the CRTC attached to the DRM device.  Also, it does setup after
attaching the CRTC to the DRM device.

Fix this by reordering the function such that we do the setup before
drm_crtc_init(): this fixes both issues.

Enable lock claims that it is serializing tve_enable/disable calls.
However, DRM already serialises mode sets with a mutex, which prevents
encoder/connector functions being called concurrently.  Secondly,
holding a spinlock while calling clk_prepare_enable() is wrong; it
will cause a might_sleep() warning should that debugging be enabled.
So, let's just get rid of the enable_lock.

The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.

But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
...  nud ...") does not trigger a netlink notification.  This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.

This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.

At some point, Measurement Computing / ComputerBoards redesigned the
PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip.
This meant they had to put their hardware registers in the PCI BAR 2
region instead of PCI BAR 1.  Unfortunately, they kept the same PCI
device ID for the new design.  This means the driver recognizes the
newer cards, but doesn't work (and is likely to screw up the local
configuration registers of the PLX chip) because it's using the wrong
region.

Since  the PCI subvendor and subdevice IDs were both zero on the old
design, but are the same as the vendor and device on the new design, we
can tell the old design and new design apart easily enough.  Split the
existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new
entries, referenced by different entries in the PCI device ID table
`pci_8255_pci_table[]`.  Use the same board name for both entries.

Merge tag 'iio-fixes-for-3.13c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

Jonathan writes:

Third set of fixes for IIO in the 3.13 cycle.

* Fix for a bug in the new cm36651 driver where it told the IIO driver it
  was providing a decimal part, but then didn't.  Now it correctly tells the
  IIO core that it is only providing an integer value.  This prevents random
  incorrect values being output on a sysfs read.

* 3 fixes where drivers were miss specifying the endianness of their channels
  as output through the buffer interface.  These were discovered whilst
  removing the terrible IIO_ST macro once and for all.  The result is that
  userspace may be informed that the buffer elements are being output as
  little endian (on little endian platforms) when infact they are big endian.
  Thus userspace will handle them incorrectly.  This incorrect buffer
  element specification is provided as sysfs attributes under
  iio:deviceN/scan_elements.

Note this also sets the endianness to big endian whereas it would

this is a bug fix on LE platforms.

A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel.  Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

staging:iio:mag:hmc5843 fix incorrect endianness of channel as a result of missuse of the IIO_ST macro.

This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness.  This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
