From d11f54b7d1d40463024be3b40ab7be2c8a84fa43 Mon Sep 17 00:00:00 2001 From: James Smart Date: Sat, 4 Mar 2017 09:30:24 -0800 Subject: [PATCH] scsi: lpfc: fix missing spin_unlock on sql_list_lock From: Colin Ian King In the case where sglq is null, the current code just returns without unlocking the spinlock sql_list_lock. Fix this by breaking out of the while loop and the exit path will then unlock and return NULL as was the original intention.
