The aperture devres node was registered after\nthe DRM device node, so devres_release_all() unmaps the aperture before\nthe DRM device release callback fires amdgpu_device_fini_sw(). IP\nsw_fini callbacks (e.g. vcn_v4_0_sw_fini) write to fw_shared through a\npointer derived from aper_base_kaddr, causing a kernel page fault on\nprobe failure / rollback:\n\n  BUG: unable to handle page fault ...
