From a4e1d0b76e7b32c0839e72679c530445172a2564 Mon Sep 17 00:00:00 2001 From: Bart Van Assche <bvanassche@acm.org> Date: Mon, 15 Aug 2022 10:00:43 -0700 Subject: [PATCH] block: Change the return type of blk_mq_map_queues() into void Since blk_mq_map_queues() and the .map_queues() callbacks always return 0, change their return type into void. Most callers ignore the returned value anyway. Cc: Christoph Hellwig <hch@lst.de> Cc: Jason Wang <jasowang@redhat.com> Cc: Keith Busch <kbusch@kernel.org> Cc: Martin K.
