Subject: [PATCH 4.19 047/321] scsi: target/tcmu: Fix queue_cmd_ring() declaration

From: Bart Van Assche <bvanassche@....org>

[ Upstream commit e7f411049f5164ee6db6c3434c07302846f09990 ]

This patch does not change any functionality but avoids that sparse
complains about the queue_cmd_ring() function and its callers.

Fixes: 6fd0ce79724d ("tcmu: prep queue_cmd_ring to be used by unmap wq")
