Subject: [PATCH 33/33] backlight: simplify lcd notifier
Date:   Tue, 28 May 2019 11:03:04 +0200

With all the work I've done on replacing fb notifier calls with direct
calls into fbcon the backlight/lcd notifier is the only user left.

It will only receive events now that it cares about, hence we can
remove this check.
