Subject: drm/amd: Use `amdgpu_ucode_*` helpers for DMCU
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=46fa9075dc440309e08cc5291db7a047b677f495;p=linux.git

drm/amd: Use `amdgpu_ucode_*` helpers for DMCU

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper is for symmetry on unloading.
