2020-04-25video/fbdev/riva: Remove dead codeSouptick Joarder1-18/+0
These are dead code since 3.15. These can be removed forever if no plan to use it further. Signed-off-by: Souptick Joarder <jrdr.linux@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/1587407244-32574-1-git-send-email-jrdr.linux@gmail.com
2020-04-17video: fbdev: vesafb: add missed release_regionChuhong Yuan1-5/+11
The driver forgets to free the I/O region in remove and probe failure. Add the missed calls to fix it. Since the success of request_region() is optional, add the "region" field in vesafb_par to represent whether request_region() succeeds. Then only call release_region() when "region" is not null.

The driver forgets to free irq in remove which is requested in probe. Add the missed call to fix it. Also, the position of request_irq() in probe should be put before register_framebuffer().

The driver calls register_framebuffer() in probe but does not call unregister_framebuffer() in remove. Rename current remove to __s1d13xxxfb_remove() for error handler.

2020-04-17video: fbdev: imxfb: ensure balanced regulator usageUwe Kleine-König1-6/+21
The fbdev framework doesn't care to call the .set_power callback only on changes. So the driver has to care for itself that the regulator doesn't get disabled more often than enabled. This fixes the regulator warning unbalanced disables for lcd supply which can be triggered by doing echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power twice.

2020-03-25backlight: corgi: Convert to use GPIO descriptorsLinus Walleij1-50/+18
The code in the Corgi backlight driver can be considerably simplified by moving to GPIO descriptors and lookup tables from the board files instead of passing GPIO numbers using the old API. Make sure to encode inversion semantics for the Akita and Spitz platforms inside the GPIO lookup table and drop the custom inversion semantics from the driver. All in-tree users are converted in this patch.
