Subject: drm/amdgpu: fix list add issue in vram reserve
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4e781873fa1359c9a85559b6da6548ac5b07ceb5;p=linux.git

drm/amdgpu: fix list add issue in vram reserve

The parameter order in the list_add_tail is incorrect, it causes the
reuse of ras reserved page.
