Wolfram Sang fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

This patch fixes following sparse warning:

drivers/power/wm97xx_battery.c:311:6: warning: symbol 'wm97xx_bat_set_pdata' was not declared. Should it be static?

Note that we can't just include linux/wm97xx_batt.h because the header
is deprecated, and so this pops up:

In file included from drivers/power/wm97xx_battery.c:22:
include/linux/wm97xx_batt.h:6: warning: #warning This file will be removed soon, use wm97xx.h instead!

Since wm97xx_bat_set_pdata() is also deprecated (in favour of pdata
passed via AC97 bus), just workaround the issue by declaring the
function in wm97xx_battery.c.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Mark Brown 59f25070df mfd: Update WM8350 drivers for changed interrupt numbers
The headphone detect and charger are using the IRQ numbers so need
to take account of irq_base with the genirq conversion. I obviously
picked the wrong system for initial testing.

Grazvydas Ignotas afbc74fdc5 power_supply: bq27x00: fix voltage and current units
The chip returns voltage and current in mV and mA, but
power supply class uses uV and uA, so add missing conversion.

Grazvydas Ignotas 4e924a814a power_supply: bq27x00: add status and time properties
The BQ27x00 series of chips can report time-to-empty and
time-to-full, so let's add corresponding properties.
Also report charge status based on status flag register.

Grazvydas Ignotas e20908d95e power_supply: bq27x00: add BQ27500 support
BQ27500 is newer fuel gauge chip from TI with slightly changed
register layout and some different register semantics. Add new i2c
ID for it and handle differences where needed. Also rename bq27200
functions to bq27x00, as they are no longer bq27200 specific.

Grazvydas Ignotas 97f70c23a1 power_supply: bq27x00: remove double endian swap
The bq27x00 registers are little endian, so just read them as such
and don't do double endian swap on LE machines.

This also gets rid of strange looking shift that was done after
reading 8bit register because endian swap in bq27x00_read() was
messing it up.
