Subject: nvme-fc: fix a missing queue put in nvmet_fc_ls_create_association
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5ca46a04a5c30c498f696b0403adf59b2c1cec61;p=linux.git

nvme-fc: fix a missing queue put in nvmet_fc_ls_create_association

[ Upstream commit 0cab4404874f2de52617de8400c844891c6ea1ce ]

As part of nvmet_fc_ls_create_association there is a case where
nvmet_fc_alloc_target_queue fails right after a new association with an
admin queue is created. In this case, no one releases the get taken in
nvmet_fc_alloc_target_assoc.  This fix is adding the missing put.
