3.16.7-ckt19 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: =?UTF-8?q?Michel=20D=C3=A4nzer?= <michel.daen...@amd.com>
commit 4281f46ef839050d2ef60348f661eb463c21cc2e upstream.
Instead of only enabling the backlight (which seems to set it to max
brightness), just re-set the current backlight level, which also takes
care of enabling the backlight if necessary.
Only the radeon_atom_encoder_dpms_dig part tested on a Kaveri laptop,
the radeon_atom_encoder_dpms_avivo part is only compile tested.
