Subject: drm/amdgpu: Fix NULL ptr on driver unload due to init failure.
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b6356df3eb9ad9ae12efb4ec37d5615065e51d8b;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu: Fix NULL ptr on driver unload due to init failure.

Problem:
When unloading due to failure amdgpu_device_fini was called twice
which was leading to NULL ptr in amdgpu_irq_disable_all.

Fix:
Call amdgpu_device_fini only once from amdgpu_driver_unload_kms.
