Merge tag 'omapdss-for-3.10-fixes' of git://gitorious.org/linux-omap-dss2/linux into drm-next

OMAPDSS fixes for 3.10:

* Compilation fix when DSI is disabled in Kconfig
* Basic deferred probe support to fix DT boot

* tag 'omapdss-for-3.10-fixes' of git://gitorious.org/linux-omap-dss2/linux:
  OMAPDSS: TFP410: return EPROBE_DEFER if the i2c adapter not found
  OMAPDSS: VENC: Add error handling for venc_probe_pdata
  OMAPDSS: HDMI: Add error handling for hdmi_probe_pdata
  OMAPDSS: RFBI: Add error handling for rfbi_probe_pdata
  OMAPDSS: DSI: Add error handling for dsi_probe_pdata
  OMAPDSS: SDI: Add error handling for sdi_probe_pdata
  OMAPDSS: DPI: Add error handling for dpi_probe_pdata
  OMAPDSS: VENC: use platform_driver_register()
  OMAPDSS: HDMI: use platform_driver_register()
  OMAPDSS: RFBI: use platform_driver_register()
  OMAPDSS: DSI: use platform_driver_register()
  OMAPDSS: SDI: use platform_driver_register()
  OMAPDSS: DPI: use platform_driver_register()
  OMAPFB: defer probe if no displays
  OMAPFB: use module_platform_driver()
  OMAPDSS: Makefile: move omapfb after panels
  OMAPDSS: DPI: fix compilation if DSI not compiled in
