[PATCH 15/48] drm/amdgpu/vcn2.5: convert internal functions to use vcn_inst

Alex Deucher alexander.deucher at amd.com
Tue Dec 10 22:53:04 UTC 2024


Pass the vcn instance structure to these functions rather
than adev and the instance number.

TODO: clean up the function internals to use the vinst state
directly rather than accessing it indirectly via adev->vcn.inst[].
