Axel Lin d974e00b95 drivers/video/backlight/s6e63m0.c: unregister backlight device and remove sysfs attribute file in s6e63m0_remove
s6e63m0_probe() registered backlight device and create sysfs attribute
files, thus s6e63m0_remove() should unregister backlight device and remove
sysfs attribute files.

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.

InKi Dae ee378a5c65 backlight: add S6E63M0 AMOLED LCD Panel driver
This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI
interface also almost features for lcd panel driver has been implemented
in here.  and I added new structure common for all the lcd panel drivers
to include/linux/lcd.h file.

LCD Panel driver needs interfaces for controlling device power such as
power on/off and reset.  these interfaces are device specific so it should
be implemented to machine code at this time, we should create new
structure for registering these functions as callbacks and also a header
file for that structure and finally registered callback functions would be
called by lcd panel driver.  such header file(including new structure for
lcd panel) would be added for all the lcd panel drivers.

If anyone provides common structure for registering such callback
functions then we could reduce unnecessary header files for lcd panel.  I
thought that suitable anyone could be include/linux/lcd.h so a new
lcd_platform_data structure was added there.

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.

André Goddard Rosa e7d2860b69 tree-wide: convert open calls to remove spaces to skip_spaces() lib function
Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.

It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
   text    data     bss     dec     hex filename
  64688     584     592   65864   10148 (TOTALS-BEFORE)
  64641     584     592   65817   10119 (TOTALS-AFTER)

Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".

and found occurrences of this pattern on 3 more files:

Since when used in this configuration the current sink and boost
convertor are very tightly coupled with a multi-stage startup for
the current sink which overlaps with the boost convertor startup
this driver bypasses the regulator API. Machine inititialisation
is responsible for ensuring that the regulators are not accessed

Mario Schwalbe c78a628849 backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5
This patch adds support for the new Apple models incorporating an Nvidia
chipset.  Apple still uses the same protocol as on older models, but the
registers moved to a different address. To do this, two sets of functions
are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH
function.

The initial code has been contributed by Hu Gang <hugang@soulinfo.com>.

The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook
Pro 5.

Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing
brightness within X doesn't work, if using Nvidia's proprietary graphics
driver with no known fix at present. Changing brightness on a text console
or using the open-source driver does work.

MacBook Pro 5 has a known bug where the initial brightness after bootup is
the last recently used brightness (in Mac OSX), while the firmware reports
maximum. Impossible to fix.

Actually, the value is correct, only semantic is wrong.

Ben Dooks b3b4dc8840 lcd: fix oops if driver only interested in .set_power
The LCD driver core calls LCD drivers when either the blanking state or
the display mode has changed, but does not make any check to see if the
called driver has a .set_mode method.

This means if a driver only has a .set_power method then the system will
OOPS on changing mode (and with the console semaphore held so you cannot
easily see the problem).

Fix the problem by ensuring that either callback is valid before use.

This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI

with integrated backlight support are recommended.
