fbdev: Switch back to struct platform_driver::remove()

2024-10-08T19:47:18Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files. Signed-off-by: Uwe Kleine-König Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: omapfb: Use backlight power constants

2024-09-30T14:35:34Z

Replace FB_BLANK_ constants with their counterparts from the backlight subsystem. The values are identical, so there's no change in functionality or semantics.

fbdev: omapfb: panel-sony-acx565akm: Simplify show_cabc_available_modes()

2024-08-30T16:42:38Z

Use sysfs_emit_at() instead of snprintf() + custom logic. Using sysfs_emit_at() is much more simple. Also, sysfs_emit() is already used in this function, so using sysfs_emit_at() is more consistent. Also simplify the logic: - always add a space after an entry - change the last space into a '\n' Finally it is easy to see that, given the size of cabc_modes, PAGE_SIZE can not be reached. So better keep everything simple (and correct). Signed-off-by: Christophe JAILLET Reviewed-by: Andi Shyti Signed-off-by: Helge Deller

backlight: Remove fb_blank from struct backlight_properties

2024-03-28T10:16:26Z

Remove the field fb_blank from struct backlight_properties and remove all code that still sets or reads it. Backlight blank status is now tracked exclusively in struct backlight_properties.state. The core backlight code keeps the fb_blank and state fields in sync, but doesn't do anything else with fb_blank. Several drivers initialize fb_blank to FB_BLANK_UNBLANK to enable the backlight. This is already the default for the state field. So we can delete the fb_blank code from core and drivers and rely on the state field.

fbdev: panel-tpo-td043mtea1: Convert sprintf() to sysfs_emit()

2024-03-21T18:37:20Z

Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit().

fbdev: omapfb/tpd12s015: Convert to platform remove callback returning void

2023-11-10T06:34:19Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller
