  drm/sti: load HQVDP firmware the first time HQVDP's plane is used
  drm/sti: fix typo issue in sti_mode_config_init
  drm/sti: set mixer background color through module param
  drm/sti: Remove local fbdev emulation Kconfig option
  drm/sti: remove redundant sign extensions
  drm/sti: hdmi use of_get_i2c_adapter_by_node interface
  drm/sti: hdmi fix i2c adapter device refcounting
  drm/sti: Do not export symbols
  drm/sti: Build monolithic driver
  drm/sti: Use drm_crtc_vblank_*() API
  drm/sti: Store correct CRTC index in events
  drm/sti: Select FW_LOADER
