3.19.8-ckt5 -stable review patch. If anyone has any objections, please let me know.
------------------
From: =?UTF-8?q?Michel=20D=C3=A4nzer?= <michel.daenzer@amd.com>
commit cd404af0c930104462aa91344f07d002cf8248ed upstream.
Take a GEM reference for and pin the new cursor BO, unpin and drop the
GEM reference for the old cursor BO in radeon_crtc_cursor_set2, and use
radeon_crtc->cursor_addr in radeon_set_cursor.
This fixes radeon_cursor_reset accidentally incrementing the cursor BO
pin count, and cleans up the code a little.
