Subject: [PATCH linux-next] drm/amdgpu/vcn: Return void from the stop_dbg_mode
There is no point in returning an int here. It only returns 0 which the caller never uses. Therefore return void and remove the unnecessary assignment.
Addresses-Coverity: 1504988 ("Unused value")
Fixes: 8da1170a16e4 ("drm/amdgpu: add VCN4 ip block support")
