Subject: sony-laptop: do not scribble keyboard backlight registers on
resume
From: Mattia Dongili <malattia@xxxxxxxx>
commit b975dc3689fc6a3718ad288ce080924f9cb7e176 upstream.
Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard
backlight settings"): avoid messing up the state on resume. Leave it to
what was before suspending as it's anyway likely that we still don't
know what value we should write to the EC registers. This fix is also
required in 3.12
