From 568981c881e20fccdbfffb073c3868dcdc012446 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix-pcf50633-really-defer-backlight-on-resume.patch
Backlight wasn't off by default on resume, so it was never really
deferred (until LCM is initialized). This fixes that and so removes
the brief white screen between pcf50633 resume and LCM init.
