drm/amdgpu/smu_v11_0: Correct behavior of restoring default tables (v2)
Previously, the syfs functionality for restoring the default powerplay table was sourcing it's information from the currently-staged powerplay table. This patch adds a step to cache the first overdrive table that we see on boot, so that it can be used later to "restore" the powerplay table v2: sqaush my original with Matt's fix Bug: https://gitlab.freedesktop.org/drm/amd/issues/1020 Signed-off-by: Matt Coffin <mcoffin13@gmail.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org # 5.5.x
