This patchset tries to move the process of converting drm_format to
vs_format into plane's atomic_check callback (instead of the
atomic_commit one, which the process currently sits) for more proper
error handling (because atomic_commit cannot fail).

In addition, because of the original flow of primary plane's
atomic_check seems to be flawed, it's also updated before filling
vs_format is added there.

Icenowy Zheng (4):
drm: verisilicon: make vs_format conversion function return int
drm: verisilicon: subclass drm_plane_state
drm: verisilicon: call atomic helper's plane state check even if no
CRTC
drm: verisilicon: fill plane's vs_format in atomic_check
