backlight: generic_bl: Remove unused function

2014-08-28T13:10:16+00:00

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?

backlight: use dev_get_platdata()

2013-11-13T03:09:16+00:00

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.

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

2012-05-29T23:22:29+00:00

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

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.

backlight: rename corgibl_limit_intensity() to genericbl_limit_intensity()

The rename of corgibl_limit_intensity is missed in commit d00ba726
("backlight: Rename the corgi backlight driver to generic").  Let's fix it
now.

backlight: add backlight type

2011-03-23T00:43:59+00:00

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.

backlight: Allow properties to be passed at registration

2010-03-16T19:47:54+00:00

Values such as max_brightness should be set before backlights are
registered, but the current API doesn't allow that. Add a parameter to
backlight_device_register and update drivers to ensure that they
set this correctly.
