Subject: drm/amd: Move AMD_IS_APU check for ASPM into top level function
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a6513de493d13f8d7501611fcc5bbaea4c799b3;p=linux.git

drm/amd: Move AMD_IS_APU check for ASPM into top level function

There is no need for every ASIC driver to perform the same check.
Move the duplicated code into amdgpu_device_should_use_aspm().
