Merge tag 'omapdrm-fixes-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux into drm-next

Fixes for omapdrm, some of which were already present in 3.14, and some which
appeared in 3.15-rc1:

- fixes for primary-plane handling which caused crashes
- fix all kinds of uninit issues which prevented from unloading the omapdrm
  module.
- fixes for HDMI enable/disable issues
