[PATCH 00/24] platform/x86: ideapad-laptop: cleanup, keyboard backlight and "always on USB charging" control support, reenable touchpad control

["Barnabás Pőcze" <pobrn@protonmail.com>]

This series contains patches that aim to bring more consistency
to the code; add keyboard backlight control support; add
"always on USB charging" control support.
Furthermore, commit 7f363145992cebf4ea760447f1cfdf6f81459683 is reverted
since it made it impossible to disable/enable the touchpad via the
ideapad-laptop module and on some devices the method implemented in the
module works correctly to disable/enable the touchpad.
