[Bug 204241] amdgpu fails to resume from suspend

https://bugzilla.kernel.org/show_bug.cgi?id=204241

--- Comment #21 from Ahzo@tutanota.com --- Created attachment 285471 --> https://bugzilla.kernel.org/attachment.cgi?id=285471&action=edit Patch to prevent kernel NULL pointer dereferences

By the way, some of the kernel NULL pointer dereferences, that can happen after a resume failure, also happen always on shutdown: RIP: 0010:build_audio_output.isra.0+0x97/0x110 [amdgpu] RIP: 0010:enable_link_dp+0x186/0x300 [amdgpu]

Attached patch prevents them.

Note that these oopses are difficult to notice on shutdown, because they only leave traces in /sys/fs/pstore, not on the disk, as they happen after unmounting.
