The error code should be negative. Since this ends up in the default case
anyway, this is harmless, but it's less confusing to negate it. Also,
later patches will require a negative error code here.

The LP87565 chip is a power management IC for Portable Navigation Systems
and Tablet Computing devices. It contains the following components:
- Configurable Bucks(Single and multi-phase).
- Configurable General Purpose Output Signals (GPO).
The LP87565-Q1 variant device uses two 2-phase outputs configuration,
Buck0 is master for Buck0/1 output and Buck2 is master for Buck2/3
output.

Currently we request the irq when probing, but never free it. So after
unbind ec driver, this irq will be left requested, which would break
the next bind:

regmap access ranges. This applies to both da9061_aa_readable_ranges[]
and da9061_aa_writeable_ranges[].
This change is to correct the DA9061 chip model and align it with the
latest DA9061 Datasheet.
This register previously appeared in the DA9061 Datasheet, Revision 3.2,
01-Mar-2016 and has been removed from later DA9061 datasheet from Dialog,

On x86 the AXP288 PMIC provides an ACPI OpRegion handler, which must be
available before other drivers using it are loaded, which can only be
ensured if the MFD, OpRegion and i2c-bus drivers are built-in.
Since the AXP20x MFD code is used on non x86 too we cannot simply change
this into a bool, I've tried some Kconfig magic with if x86 but I could
not get this working correctly, so this commit just documents that this
should be built-in on x86, which fixes errors like these during boot:

Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non
upstreamed CHT Whiskey Cove PMIC patches.
This is a somewhat minimal version which adds irqchip support and cells
for: ACPI PMIC opregion support, the i2c-controller driving the external
charger irc and the pwrsrc/extcon block.
Further cells can be added in the future if/when drivers are upstreamed
for them.
[The above patch caused a build error on some archetectures]
From: Arnd Bergmann <arnd@arndb.de>
I ran into a build error on ARM with a platform that has a non-standard
clk implementation:
drivers/clk/clk.o: In function `clk_disable':
clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here
The problem is a device driver that uses 'select COMMON_CLK', which is
generally a bad idea: selecting a subsystem should only be done from
a platform, otherwise we run into circular dependencies. The same driver
also selects 'GPIOLIB' and 'I2C', which has a similar effect.
This turns all three into 'depends on', as it should be.
Finally, we can limit the build to x86, unless we are compile testing.

The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be
available before other drivers using it are loaded, which is why
INTEL_SOC_PMIC is a bool.
Just having the driver is not enough, the driver for the i2c-bus must
also be built in, to ensure this, this patch adds a select for it.
This fixes errors like these during boot:
mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA
ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] (20170119/evregion-166)

acpi 80860F14:02: Failed to change power state to D0
While at it this patch also changes the human readable name of the Kconfig
option to make clear the INTEL_SOC_PMIC option selects support for the
Intel Crystal Cove PMIC and documents why this is a bool.

When a CIFS filesystem is mounted with the forcemand option and the
following command is run on it, lockdep warns about a circular locking
dependency between CifsInodeInfo::lock_sem and the inode lock.
while echo foo > hello; do :; done & while touch -c hello; do :; done
cifs_writev() takes the locks in the wrong order, but note that we can't
only flip the order around because it releases the inode lock before the
call to generic_write_sync() while it holds the lock_sem across that
call.
But, AFAICS, there is no need to hold the CifsInodeInfo::lock_sem across
the generic_write_sync() call either, so we can release both the locks
before generic_write_sync(), and change the order.

Pull mnt namespace updates from Eric Biederman:
"A big break-through came during this development cycle as a way was
found to maintain the existing umount -l semantics while allowing for
optimizations that improve the performance. That is represented by the
first change in this series moving the reparenting of mounts into
their own pass. This has allowed addressing the horrific performance
of umount -l on a carefully crafted tree of mounts with locks held
(0.06s vs 60s in my testing). What allowed this was not changing where
umounts propagate to while propgating umounts.
The next change fixes the case where the order of the mount whose
umount are being progated visits a tree where the mounts are stacked
upon each other in another order. This is weird but not hard to
implement.
The final change takes advantage of the unchanging mount propgation
tree to skip parts of the mount propgation tree that have already been
visited. Yielding a very nice speed up in the worst case.
There remains one outstanding question about the semantics of umount -l
that I am still discussiong with Ram Pai. In practice that area of the
semantics was changed by 1064f874abc0 ("mnt: Tuck mounts under others
instead of creating shadow/side mounts.") and no regressions have been
reported. Still I intend to finish talking that out with him to ensure
there is not something a more intense use of mount propagation in the
future will not cause to become significant"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
mnt: Make propagate_umount less slow for overlapping mount propagation trees
mnt: In propgate_umount handle visiting mounts in any order
mnt: In umount propagation reparent in a separate pass

Pull GFS2 updates from Bob Peterson:
"We've got eight GFS2 patches for this merge window:
- Andreas Gruenbacher has four patches related to cleaning up the
GFS2 inode evict process. This is about half of his patches
designed to fix a long-standing GFS2 hang related to the inode
shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
memory and blocks on the shrinker.
These four patches have been well tested. His second set of patches
are still being tested, so I plan to hold them until the next merge
window, after we have more weeks of testing. The first patch
eliminates the flush_delayed_work, which can block.
- Andreas's second patch protects setting of gl_object for rgrps with
a spin_lock to prevent proven races.
- His third patch introduces a centralized mechanism for queueing
glock work with better reference counting, to prevent more races.
-His fourth patch retains a reference to inode glocks when an error
occurs while creating an inode. This keeps the subsequent evict
from needing to reacquire the glock, which might call into DLM and
block in low memory conditions.
- Arvind Yadav has a patch to add const to attribute_group
structures.
- I have a patch to detect directory entry inconsistencies and
withdraw the file system if any are found. Better that than silent
corruption.
- I have a patch to remove a vestigial variable from glock
structures, saving some slab space.
- I have another patch to remove a vestigial variable from the GFS2
in-core superblock structure"
