drivers/video/backlight/s6e63m0.c: fix corruption storing gamma mode

2012-03-16T00:03:04Z

strict_strtoul() writes a long but ->gamma_mode only has space to store an int, so on 64 bit systems we end up scribbling over ->gamma_table_count as well. I've changed it to use kstrtouint() instead. Signed-off-by: Dan Carpenter Acked-by: Inki Dae Signed-off-by: Florian Tobias Schandinat Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/video/backlight/adp88x0_bl.c: fix bit testing logic

2012-01-23T16:38:48Z

We need to write new value if the bit mask fields of new value is not equal to old value. It does not make sense to write new value only when all the bit_mask bits are zero. Signed-off-by: Axel Lin Cc: Michael Hennerich Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: convert pwm_bl to dev_pm_ops

2012-01-11T00:30:48Z

Should be no functional changes, mainly a reorganisation to support future work. [akpm@linux-foundation.org: fix CONFIG_PM=n build] Signed-off-by: Mark Brown Cc: Richard Purdie Cc: Florian Tobias Schandinat Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: convert platform_lcd to devm_kzalloc()

2012-01-11T00:30:48Z

Saves some error handling code and eliminates a class of leaks. Signed-off-by: Mark Brown Cc: Richard Purdie Cc: Florian Tobias Schandinat Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: use kstrtoul()

2012-01-11T00:30:48Z

The usage of simple_strtoul() or strict_strtoul() is not preferred. Thus, kstrtoul should be used. This patch also fixes checkpatch error as follows: ERROR: space required after that ',' (ctx:VxV) Signed-off-by: Jingoo Han Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight/ld9040.c: regulator control in the driver

2012-01-11T00:30:48Z

This patch supports regulator power control in the driver. Current ld9040 driver was controlled power on/off sequence by callback function in the board file. But, by doing this, there's no need to register lcd power on/off callback function in the board file.

backlight: convert drivers/video/backlight/* to use module_platform_driver()

2012-01-11T00:30:48Z

Convert the drivers in drivers/video/backlight/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

backlight: remove ADX backlight device support

2012-01-11T00:30:48Z

Support for the Avionic Design Xanthos backlight device got added in commit 3b96ea9ef8 ("backlight: Add support for the Avionic Design Xanthos backlight device."). That support depends on ARCH_PXA_ADX. The code that should have provided that Kconfig symbol never got submitted. It has never been possible to even build this driver. Remove it.
