[PATCH v5 39/45] drm/amd: Use `amdgpu_ucode_*` helpers for VCE

From: Mario Limonciello
Date: Wed Jan 04 2023 - 11:48:12 EST


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.
