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 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.
