From: Guchun Chen Date: Sat, 18 Sep 2021 05:43:41 +0000 (+0800) Subject: drm/amdgpu: move amdgpu_virt_release_full_gpu to fini_early stage X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6effad8abe0ba4db3d9c58ed585127858a990f35;p=linux.git drm/amdgpu: move amdgpu_virt_release_full_gpu to fini_early stage adev->rmmio is set to be NULL in amdgpu_device_unmap_mmio to prevent access after pci_remove, however, in SRIOV case, amdgpu_virt_release_full_gpu will still use adev->rmmio for access after amdgpu_device_unmap_mmio. The patch is to move such SRIOV calling earlier to fini_early stage.
