drm/amd/display: fix ref count leak in amdgpu_drm_ioctl

2020-09-03T09:21:16+00:00

[ Upstream commit 5509ac65f2fe5aa3c0003237ec629ca55024307c ]

in amdgpu_drm_ioctl the call to pm_runtime_get_sync increments the
counter even in case of failure, leading to incorrect
ref count. In case of failure, decrement the ref count before returning.

drm/amdgpu: just suspend the hw on pci shutdown

2016-12-07T16:17:21+00:00

We can't just reuse pci_remove as there may be userspace still
doing things.

drm/amdgpu: add some error handling to amdgpu_init v2

drm/amd: fix scheduler fence teardown order v2

2016-10-31T16:43:20+00:00

Some fences might be alive even after we have stopped the scheduler leading
to warnings about leaked objects from the SLUB allocator.

Fix this by allocating/freeing the SLUB allocator from the module
init/fini functions just like we do it for hw fences.

v2: make variable static, add link to bug
