Subject: nvme-pci: unquiesce dead controller queues
X-Git-Tag: v4.19~826^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1d39e6928cbd0eb737c51545210b5186d5551ba1;p=platform%2Fkernel%2Flinux-rpi.git

nvme-pci: unquiesce dead controller queues

This patch ensures the nvme namsepace request queues are not quiesced
on a surprise removal. It's possible the queues were previously killed
in a failed reset, so the queues need to be unquiesced to ensure all
requests are flushed to completion.
