[PATCH v1 0/3] drm/panel: update backlight support for samsung panels

[Sam Ravnborg]

Update the backlight handling in three samsung panels.
  - Use devm_ functions to automate cleanup
  - Utilize backlight support in drm_panel
  - Introduce a register backlight helper in all panels
    Using the same pattern in all panels makes it simpler
    to read the code.

With this change the backlight handling in these panels
is now much more like what we see in other panels.

Testing or any other feedback appreciated!
