drm/amd/pm: workaround for compute workload type on some skus
On smu 13.0.0, the compute workload type cannot be set on all the skus due to some other problems. This workaround is to make sure compute workload type can also run on some specific skus. v2: keep the variable consistent Signed-off-by: Kenneth Feng <kenneth.feng@amd.com> Acked-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Feifei Xu <Feifei.Xu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org # 6.1.x
