Subject: nvmet: remove extra variable in id-ns handler
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3999434b6ce6fa452128c36cbb5017f0cd347615;p=linux.git

nvmet: remove extra variable in id-ns handler

In nvmet_execute_identify_ns() local variable ctrl is accessed only in
one place, remove that and directly use it from nvmet_req->sq->ctrl.
