Merge branch 'drm-3.17-rc2-sti-fixes' of git://git.linaro.org/people/benjamin.gaignard/kernel into drm-fixes

I have tested the 6 patches send on mailing list since you merge the sti driver.
I haven't seen issue with those patches except for the missing
dependency on Kconfig
where I have change "depends on" to "select".

* 'drm-3.17-rc2-sti-fixes' of git://git.linaro.org/people/benjamin.gaignard/kernel:
  drm: sti: Add missing dependency on RESET_CONTROLLER
  drm: sti: Make of_device_id array const
  drm: sti: Fix return value check in sti_drm_platform_probe()
  drm: sti: hda: fix return value check in sti_hda_probe()
  drm: sti: hdmi: fix return value check in sti_hdmi_probe()
  drm: sti: tvout: fix return value check in sti_tvout_probe()
