[PATCH] drm/radeon: make crtc number check in radeon_get_vblank_timestamp_kmsconsistent with other functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



the crtc check in radeon_get_vblank_timestamp_kms should be against
the num_crtc field in radeon_device not against num_crtcs in drm_device
like it's done in all other functions that handle crtc
