Just a minor nit on this cover letter; you have it listed as [v4 0/6]
but there are only 5 patches in the series in this version so the cover
letter title should be updated too.

This patchset tries to fix several memory leakages/invalid memory
accesses on error handling path during GPU driver loading/unloading.
They applies to:
https://gitlab.freedesktop.org/agd5f/linux.git amd-staging-drm-next
v4:
1) drop patch 1 in v3
2) split out amdxcp related change into a dedicated patch
3) use `guard(mutex)` instead of mutex_lock/unlock().
4) move patch 6 in v3 to next patch set
v3:
1) drop first patch of v2
2) rework the 0003/0004 patches of v2 according to review comments
3) add patch 0004 to fix possible resource leakage in amdgpu_pci_probe()
v2:
1) rebased to https://gitlab.freedesktop.org/agd5f/linux.git branch
amd-staging-drm-next.
2) removed the first patch, which is unnecessary.
3) add amdgpu_xcp_drm_dev_free() in patch 0003 to enhance amdxcp
driver to better support device remove and error handling.
4) reworked patch 0005 to fix it in amdgpu instead of drm core.
