From f170396c14243d307e2f479af142fd7356b3bd2a Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 3 Feb 2017 19:38:54 +0000 Subject: [PATCH] scsi: fix memory leak of sdpk on when gd fails to allocate On an allocation failure of gd, the current exit path is via out_free_devt which leaves sdpk still allocated and hence it gets leaked. Fix this by correcting the order of resource free'ing with a change in the error exit path labels.
