backlight: max8925_bl: Fix Device Tree node lookup

2018-07-03T09:21:32+00:00

commit d1cc0ec3da23e44c23712579515494b374f111c9 upstream. Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent mfd node was also prematurely freed, while the child backlight node was leaked.

backlight: Remove .owner field for drivers using module_platform_driver

2014-08-28T13:09:48+00:00

This patch removes the superflous .owner field for drivers which use the module_platform_driver or platform_driver_register api, as this is overriden in __platform_driver_register. Signed-off-by: Peter Griffin Signed-off-by: Lee Jones

backlight: max8925_bl: use devm_backlight_device_register()

2013-11-13T03:09:18+00:00

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

mfd: max8925: fix dt code for backlight

2013-07-25T23:57:00+00:00

The device-tree enablement for max8925 has several problems, but besides the bindings being wrong (and not having seen review) there's also some bad coding practices on how to fill in the platform_data from device tree. I came across this since it causes a warning when compiling mmp2_defconfig, and instead of doing the minimal fix to silence the warning, I restructured the code a bit. This silences the warning: drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe': drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value] Note that the bindings themselves need to be revisited too, but that will affect more than just the backlight driver and is best done separately; this just fixes the bad code for the backlight driver.

drivers/video/backlight/max8925_bl.c: drop devm_kfree of devm_kzalloc'd data

2012-12-18T01:15:16+00:00

devm_kfree() allocates memory that is released when a driver detaches. Thus, there is no reason to explicitly call devm_kfree in probe or remove functions. Signed-off-by: Jingoo Han Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
