According to the datasheet:
The LDO_CTRL registers are used to set the output voltage of LDO1 and LDO2.
LDO_CTRL[7] and LDO_CTRL[3] are reserved and should always be written to 0.

Thus the mask for TPS65023_LDO_1 and TPS65023_LDO_2 should be 0x07 and 0x70
respectively.

The devm_kzalloc function eliminates the need for manual resource releasing
and simplify error handling. Resources allocated by devm_* are freed
automatically on driver detach.

Thus adding kfree calls here will introduce double free bug.

The memory of desc array and the pointers to the rdev[] are allocated by
devm_kzalloc call for struct palmas_pmic.

struct palmas_pmic {
        struct palmas *palmas;
        struct device *dev;
        struct regulator_desc desc[PALMAS_NUM_REGS];
        struct regulator_dev *rdev[PALMAS_NUM_REGS];

        int smps123;
        int smps457;

        int range[PALMAS_REG_SMPS10];
};

Which means we should not call kfree for pmic->rdev and pmic->desc.

Pull device-mapper updates from Alasdair G Kergon:
 "Improve multipath's retrying mechanism in some defined circumstances
  and provide a simple reserve/release mechanism for userspace tools to
  access thin provisioning metadata while the pool is in use."

* tag 'dm-3.5-changes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm:
  dm thin: provide userspace access to pool metadata
  dm thin: use slab mempools
  dm mpath: allow ioctls to trigger pg init
  dm mpath: delay retry of bypassed pg
  dm mpath: reduce size of struct multipath

This patch implements two new messages that can be sent to the thin
pool target allowing it to take a snapshot of the _metadata_.  This,
read-only snapshot can be accessed by userland, concurrently with the
live target.

Only one metadata snapshot can be held at a time.  The pool's status
line will give the block location for the current msnap.

Since version 0.1.5 of the userland thin provisioning tools, the
thin_dump program displays the msnap as follows:

    thin_dump -m <msnap root> <metadata dev>

Available here: https://github.com/jthornber/thin-provisioning-tools

Now that userland can access the metadata we can do various things
that have traditionally been kernel side tasks:

     i) Incremental backups.

     By using metadata snapshots we can work out what blocks have
     changed over time.  Combined with data snapshots we can ensure
     the data doesn't change while we back it up.

     A short proof of concept script can be found here:

     https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb

     ii) Migration of thin devices from one pool to another.

     iii) Merging snapshots back into an external origin.

     iv) Asyncronous replication.

After the failure of a group of paths, any alternative paths that
need initialising do not become available until further I/O is sent to
the device.  Until this has happened, ioctls return -EAGAIN.

With this patch, new paths are made available in response to an ioctl
too.  The processing of the ioctl gets delayed until this has happened.

Instead of returning an error, we submit a work item to kmultipathd
(that will potentially activate the new path) and retry in ten
milliseconds.

Note that the patch doesn't retry an ioctl if the ioctl itself fails due
to a path failure.  Such retries should be handled intelligently by the
code that generated the ioctl in the first place, noting that some SCSI
commands should not be retried because they are not idempotent (XOR write
commands).  For commands that could be retried, there is a danger that
if the device rejected the SCSI command, the path could be errorneously
marked as failed, and the request would be retried on another path which
might fail too.  It can be determined if the failure happens on the
device or on the SCSI controller, but there is no guarantee that all
SCSI drivers set these flags correctly.

If I/O needs retrying and only bypassed priority groups are available,
set the pg_init_delay_retry flag to wait before retrying.

If, for example, the reason for the bypass is that the controller is
getting reset or there is a firmware upgrade happening, retrying right
away would cause a flood of log messages and retries for what could be a
few seconds or even several minutes.

Merge fixups for the mac NLS tables from Andrew.

* emailed from Andrew Morton, and one cleanup by me:
  nls: fix (and rename) mac NLS table files and config options
  fs/nls/Makefile: remove bogus CONFIG_ assignments

The config options in the Kconfig file (with _CODEPAGE_ in the name)
didn't match the config option name in the Makefile (no _CODEPAGE_).

And both of them were of the hard-to-read MACXYZZY variety, which made
them hard to parse for normal humans: MACROMAN easily reads as "macro
man", not as "Mac Roman".

So rename the options to be consistent, and be NLS_MAC_xyzzy.  Rename
the files to be mac-xyzzy.c too, and drop the "nls" part entirely (it's
already in the directory name).
