[PATCH v2 00/28] backlight: lcd: Remove fbdev dependencies

[Thomas Zimmermann <tzimmermann@suse.de>]

This series removes most dependencies on fbdev from the lcd subsystem
and its drivers.

Patches 1 to 3 rework the fbdev notifier, the fbdev's fb_info can
now refer to a dedicated lcd device, and lcd defines constants for
power states. These changes resemble similar changes to the backlight
code.

Patches 4 to 19 update lcd drivers to the new interfaces and perform
minor cleanups during the process. Patches 20 to 24 update fbdev
drivers and patch 25 updates the picolcd driver from the hid subsystem.

Patches 25 to 28 finally clean up various lcd interfaces and files.

This patchset is part of a larger effort to implement the lcd code
without depending on fbdev. Similar patches have been sent out for
the backlight subsystem, such as in [1] and [2].

Hopefully this series can be merged at once through the lcd tree.

v2:
- use guard(mutex) (Daniel)
- fix typos in various commit descriptions (Daniel)
