[Intel-gfx] [PATCH 04/11] drm/i915: add SNB video sprite support

[Inki Dae]

Hi, Jesse.

drm_plane structure has format_types and format_conunt that they was set at 
booting time. but they aren't used anywhere. at intel_update_plane(), I guess 
they could be used to check if the format type(fb->pixel_format) from setplane
() is supported or not, comparing to plane->format_types[n]; otherwise, could 
you please tell me about the purpose that format_types[] and format_count are 
used?

Thank you,
Inki Dae.
