Subject: [PATCH 58/69] DSS2: Don't touch plane coordinates when changing fb->ovl mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
When attaching overlays to a framebuffer via the 'overlays' sysfs file
do not touch the planes' coordinates. Without this change attaching
VID2 to a framebuffer which already has VID1 attached would cause VID1
to be reset to position 0,0 and scaled to 1:1 size. Also call
omapfb_apply_changes() only once after all the overlays have been
attached to avoid fiddling with all the overlays several times.
