drm/amdgpu: disable BAR resize on Dell G5 SE
There was a quirk added to add a workaround for a Sapphire RX 5600 XT Pulse that didn't allow BAR resizing. However, the quirk caused a regression with runtime pm on Dell laptops using those chips, rather than narrowing the scope of the resizing quirk, add a quirk to prevent amdgpu from resizing the BAR on those Dell platforms unless runtime pm is disabled. v2: update commit message, add runpm check Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/1707 Fixes: 907830b0fc9e ("PCI: Add a REBAR size quirk for Sapphire RX 5600 XT Pulse") Reviewed-by: Lijo Lazar <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
