Looks fine to me, but hoping to get an RB from Christian now that we're moving

Subject: [PATCH] drm/amdgpu: Report firmware versions with sysfs v2
[CAUTION: External Email]
Firmware versions can be found as separate sysfs files at:
/sys/class/drm/cardX/device/fw_version (where X is the card number) The
firmware versions are displayed in hexadecimal.
v2: Moved sysfs files to subfolder
