+Subject: [PATCH] change-backlight-level-not-forced-up-on-resume.patch
+
+We at least always enabled backlight on resume, this patch
+changes us to set backlight back to last requested backlight
+brightness level on resume.  Note it means that you can
+resume with screen blanked, but it should come back if that
+happened with touchscreen action as usual.
+
+/sys/class/backlight/pcf50633-bl/actual_brightness
+and
+/sys/class/backlight/pcf50633-bl/brightness
+
+seem to agree after resume when reportedly they didn't before.
+
