Subject: [PATCH] drm/amd/pm: fix reading SMU FW version from amdgpu_firmware_info on YC
Git-commit: dcd10d879a9d1d4e929d374c2f24aba8fac3252b
Patch-mainline: v5.16-rc6
References: git-fixes
This value does not get cached into adev->pm.fw_version during
startup for smu13 like it does for other SMU like smu12.
