backlight: generic-bl: Remove DRIVER1 state

2018-04-30T12:25:14Z

Nothing in the entire tree ever sets this, which means this is dead code. Remove it. Signed-off-by: Daniel Vetter Acked-by: Daniel Thompson Reviewed-by: Jani Nikula Signed-off-by: Lee Jones

backlight: generic_bl: Remove unused function

2014-08-28T13:10:16Z

genericbl_limit_intensity() is exported, but it is never called anywhere else. Fix the following sparse warning: drivers/video/backlight/generic_bl.c:59:6: warning: symbol 'genericbl_limit_intensity' was not declared. Should it be static? Signed-off-by: Fabio Estevam Signed-off-by: Lee Jones

backlight: generic_bl: use devm_backlight_device_register()

2013-11-13T03:09:17Z

Use devm_backlight_device_register() to make cleanup paths simpler. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: use dev_get_platdata()

2013-11-13T03:09:16Z

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/video/backlight/generic_bl.c: use dev_info() instead of pr_info()

2013-04-30T01:28:15Z

dev_info() is preferred to pr_info(). Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: generic_bl: fix checkpatch warning

2012-12-18T01:15:14Z

This patch fixes the checkpatch warning as below: WARNING: space prohibited between function name and open parenthesis '(' Signed-off-by: Jingoo Han Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: generic_bl: use pr_info() instead of printk()

2012-05-29T23:22:29Z

Use pr_info() instead of printk() to allow dynamic debugging. The pr_fmt prefix for pr_ macros is used. Also fix checkpatch warnings as below: WARNING: printk() should include KERN_ facility level [akpm@linux-foundation.org: use KBUILD_MODNAME, per Joe] Signed-off-by: Jingoo Han Cc: Richard Purdie Cc: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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: rename corgibl_limit_intensity() to genericbl_limit_intensity()

2011-11-01T00:30:54Z

The rename of corgibl_limit_intensity is missed in commit d00ba726 ("backlight: Rename the corgi backlight driver to generic"). Let's fix it now. Signed-off-by: Axel Lin Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: add backlight type

2011-03-23T00:43:59Z

There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.
