Title
drm/amdgpu: Fix kernel panic during driver load failure
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix kernel panic during driver load failure Avoid kernel panic if MES init fails during driver load. The KIQ ring is falsely marked as ready as ASICs that use MES, KIQ is owned by MES. BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:gfx_v12_1_wait_reg_mem+0x5a/0x1f0 [amdgpu] Call Trace: gfx_v12_1_ring_emit_reg_write_reg_wait+0x1f/0x30 [amdgpu] amdgpu_gmc_fw_reg_write_reg_wait+0xb2/0x190 [amdgpu] amdgpu_gmc_flush_gpu_tlb+0x1cc/0x230 [amdgpu] amdgpu_gart_invalidate_tlb+0x81/0xa0 [amdgpu] amdgpu_gart_unbind+0x72/0x90 [amdgpu] amdgpu_ttm_backend_unbind+0xa4/0xb0 [amdgpu] amdgpu_ttm_tt_unpopulate+0x13/0xd0 [amdgpu] amdttm_tt_unpopulate+0x29/0x70 [amdttm] ttm_bo_put+0x1eb/0x360 [amdttm] amdgpu_bo_free_kernel+0xf9/0x1f0 [amdgpu] amdgpu_ih_ring_fini+0x5a/0x90 [amdgpu] amdgpu_irq_fini_hw+0x58/0x80 [amdgpu] amdgpu_device_fini_hw+0x4e0/0x5b0 [amdgpu] amdgpu_driver_load_kms+0x60/0xa0 [amdgpu] amdgpu_pci_probe+0x28e/0x6d0 [amdgpu] pci_device_probe+0x19f/0x220 really_probe+0x1ed/0x340 driver_probe_device+0x1e/0x80 __driver_attach+0xd3/0x1a0 bus_for_each_dev+0x68/0xa0 bus_add_driver+0x19f/0x270 driver_register+0x5d/0xf0 do_one_initcall+0xac/0x200 do_init_module+0x1ec/0x280 __se_sys_finit_module+0x2de/0x310 do_syscall_64+0x6a/0x250 entry_SYSCALL_64_after_hwframe+0x4b/0x53 (cherry picked from commit 4623b958dd6da0f4c3026afdf330626a09ecb0f0)
