Subject: scsi: remove an extra queue reference
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3725e36dcd217fd4f23240badaa8deb0c721a55c;p=users%2Fhch%2Fblock.git

scsi: remove an extra queue reference

Now that blk_mq_destroy_queue does not release the queue reference, there
is no need for a second queue reference to be held by the scsi_device.
