Subject: drm/amdgpu: Remove superfluous NULL check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1625951a3a7bdd776d38f2cdd35f72a795e82df0;p=linux.git

drm/amdgpu: Remove superfluous NULL check

The DRM device is a static member of
the amdgpu device structure and as such
always exists, so long as the PCI and
thus the amdgpu device exist.
