backlight: platform_lcd: Constify lcd_ops

2024-05-03T09:45:28+00:00

'struct lcd_ops' is not modified by core backlight code, so it can be made const for increased code safety. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20240424-video-backlight-lcd-ops-v2-13-1aaa82b07bc6@kernel.org Signed-off-by: Lee Jones

Revert "drivers/video/backlight/platform_lcd.c: add support for device tree based probe"

2022-07-13T08:11:21+00:00

This reverts commit 52e842432f36d5b15227d0ee0d2aa3d2bc3cc0b2. The DT support never would have worked because there's no platform_data providing ops. There's not any documented binding for it either.

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: platform_lcd: remove unnecessary OOM messages

2014-04-03T23:21:11+00:00

The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: platform_lcd: use devm_lcd_device_register()

2013-11-13T03:09:19+00:00

Use devm_lcd_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

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. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
