2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-08-29backlight: ams369fg06: Remove 'else' after a returnJingoo Han
Fixed the following checkpatch warning. WARNING: else is not generally useful after a break or return Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-06-23backlight: Remove trivial get_brightness implementationsAndrzej Hajda
Since backlight core returns props.brightness in case get_brightness is not implemented trivial implementations are not needed anymore. Acked-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2013-11-13backlight: ams369fg06: use devm_{backlight,lcd}_device_register()Jingoo Han
Use devm_backlight_device_register() and devm_lcd_device_register() to make cleanup paths simpler. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-11-13backlight: use dev_get_platdata()Jingoo Han
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.

2013-04-29drivers/video/backlight/ams369fg06.c: convert ams369fg06 to dev_pm_opsJingoo Han
Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-02-27drivers/video/backlight/ams369fg06.c: make power_on() call optionalJingoo Han
This patch makes power_on() call optional. The voltage source can be provided to some boards using ams369fg06 panel, thus in this case, power on/off sequence is not necessary.

Use the wrapper function for getting the driver data using backlight_device instead of using dev_get_drvdata with &bd->dev, so we can directly pass a struct backlight_device.

2013-02-21backlight: ams369fg06: remove redundant variable 'before_power'Jingoo Han
'before_power' was used to check the previous status when resume() is called. However, FB_BLANK_POWERDOWN was used in suspend() all the time, so there is no need to check the previous status. Also, redundant return variables are removed to reduce the code.

2012-05-29blacklight: remove redundant spi driver bus initializationLars-Peter Clausen
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment.

2011-10-31video: Add module.h to drivers/video files who really use it.Paul Gortmaker
They were getting this implicitly by an include of module.h from device.h -- but we are going to clean that up and break that include chain, so include module.h explicitly now. [ with contributions from Axel Lin <axel.lin@gmail.com> ] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

registered Since commit a19a6ee "backlight: Allow properties to be passed at registration" and commit bb7ca74 "backlight: add backlight type", we can set backlight type and max_brightness before backlights are registered. Some newly added drivers did not set it properly, let's fix it.
