    Subject[PATCH AUTOSEL 4.19 022/206] drm/amdgpu/powerplay/smu7: fix AVFS handling with custom powerplay table
    Date
    From: Alex Deucher <alexander.deucher@amd.com>

    [ Upstream commit 901245624c7812b6c95d67177bae850e783b5212 ]

    When a custom powerplay table is provided, we need to update
    the OD VDDC flag to avoid AVFS being enabled when it shouldn't be.
