It seems unfortunate to me that __pm_runtime_barrier() can cause 
pm_request_resume() to hang. Would it be safe to remove the
cancel_work_sync() call from __pm_runtime_barrier() since
pm_runtime_work() calls functions that check disable_depth
when processing RPM_REQ_SUSPEND and RPM_REQ_AUTOSUSPEND? Would
this be sufficient to fix the reported deadlock?

Thanks,

Bart.
