[PATCH v7 08/16] drm/amdgpu: Convert driver sysfs attributes to static attributes
Andrey Grodzovsky
andrey.grodzovsky at amd.com
Wed May 12 14:26:40 UTC 2021
This allows to remove explicit creation and destruction
of those attrs and by this avoids warnings on device
finalizing post physical device extraction.
v5: Use newly added pci_driver.dev_groups directly
