Applied.
Thanks,

> This patch renames check_timing to check_mode and removes the
> unnecessary conversion of drm_display_mode to/from fb_videomode in
> the hdmi driver.
>
> v4:
> 1) Changed the commit message to add information related to renaming
> the callbacks to check_mode.
> 2) Changed debug message to print 1/0 for interlace mode.
>
> v3:
> 1) Replaced check_timing callbacks with check_mode.
> 2) Change the type of second parameter of check_mode callback from void
> pointer paramenter to struct drm_display_mode pointer.
>
> v2:
> 1) Removed convert_to_video_timing().
> 2) Corrected DRM_DEBUG_KMS to print the resolution properly.
