drivers/video/backlight/platform_lcd.c: introduce probe callback

2013-04-30T01:28:18+00:00

Platform LCD devices may need to do some device-specific initialization
before they can be used (regulator or GPIO setup, for example), but
currently the driver does not support any way of doing this.  This patch
adds a probe() callback to plat_lcd_data which platform LCD devices can
set to indicate that device-specific initialization is needed.

drivers/video/backlight/platform_lcd.c: remove unnecessary ifdefs

2013-04-30T01:28:14+00:00

When the macro such as SIMPLE_DEV_PM_OPS is used, there is no need to
use '#ifdef CONFIG_PM' to prevent build error.  Thus, this patch removes
unnecessary ifdefs.

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

2012-01-11T00:30:48+00:00

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