    Subject[PATCH AUTOSEL 4.19 019/206] drm/amdgpu/powerplay: fix AVFS handling with custom powerplay table
    Date
    From: Alex Deucher <alexander.deucher@amd.com>

    [ Upstream commit 53dbc27ad5a93932ff1892a8e4ef266827d74a0f ]

    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.
