Subject: drm/amdgpu: handle polaris10/11 overlap asics (v2)
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 1d4624cd72b912b2680c08d0be48338a1629a858 upstream.
Some special polaris 10 chips overlap with the polaris11
DID range. Handle this properly in the driver.
v2: use local flags for other function calls.
