[Intel-gfx] [PATCH v7 3/8] drm/i915/vdsc: Add func to get no. of vdsc instances per pipe
Suraj Kandpal

Tue Aug 8 08:11:30 UTC 2023
We have a function that gets us the total of the vdsc engines being
used but not the no. of vdsc instances being used by each pipe.
--v6
-Change function to static
--v7
-Shorten name to intel_dsc_get_vdsc_per_pipe
