Merge tag 'topic/drm-misc-2015-10-22' of git://anongit.freedesktop.org/drm-intel into drm-next
Few more drm-misc stragglers for 4.4. Big thing is the generic probe for
imx/rockchip/armada (but the variant for msm/rpi/exynos is still missing).
Also the hdmi clocking fixes from Ville which was a lot of confusion about
which tree it should be applied to ;-)
* tag 'topic/drm-misc-2015-10-22' of git://anongit.freedesktop.org/drm-intel:
drm: correctly check failed allocation
vga_switcheroo: Constify vga_switcheroo_handler
drm/armada: Convert the probe function to the generic drm_of_component_probe()
drm/rockchip: Convert the probe function to the generic drm_of_component_probe()
drm/imx: Convert the probe function to the generic drm_of_component_probe()
drm: Introduce generic probe function for component based masters.
drm/edid: Round to closest when computing the CEA/HDMI alternate clock
drm/edid: Fix up clock for CEA/HDMI modes specified via detailed timings
