You can't invoke vic_load_firmware() while RPM is suspended. Either
replace this with RPM get/put or do something else.

Why not, I'm not seeing any HW accesses in vic_load_firmware? Although it looks like it might race with the vic_load_firmware call in vic_runtime_resume which probably needs to be fixed.

If (!vic->can_use_context)
return -ENOTSUPP;

return 0x30;

and s/ENOTSUPP/EOPNOTSUPP/

Ok.
