[PATCH v6 32/32] drm/msm/dpu: remove unused dpu_plane_validate_multirect_v2 function

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

 



From: Abhinav Kumar <quic_abhinavk@xxxxxxxxxxx>

After cleaning up the older multirect support the function
dpu_plane_validate_multirect_v2() is unused. Lets remove it.
