[PATCH v16 3/7] drm/vkms: Drop YUV formats TODO

[José Expósito]

Hi Louis,

Thanks a lot for the patches.

I'm not well versed in YUV color formats, so I did my best reading the kernel
documentation before reviewing this series... But I'll most likely ask some
basic/dump questions.

I see that you implemented support for 6 DRM_FORMAT_NV* formats, but
DRM_FORMAT_NV15, DRM_FORMAT_NV20 and DRM_FORMAT_NV30 are not implemented.

The same applies to DRM_FORMAT_Y210 or DRM_FORMAT_YUV410 among others.

Could it be useful to implement all of them in the future? If so, should we add
it to the ToDo list?
It might be a great task to get started in kernel development, as there are
already similar examples and tests.
