It may happen that the underlying device's runtime-pm is
not controlled by block-pm. So it's possible that when
commands are sent to the device, it's suspended and may not
be resumed by blk-pm. Hence explicitly resume the parent

work queue with WQ_MEM_RECLAIM flag enabled.

when the above deadlock condition is possible.
