From a4bd85203190990ad808abbd4a5dc848a950002c Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 14 Apr 2016 21:20:34 +0300 Subject: [PATCH] scsi_dh_alua: uninitialized variable in alua_rtpg() It's possible to use "err" without initializing it. If it happens to be a 2 which is SCSI_DH_RETRY then that could cause a bug. Bart Van Assche pointed out that we should probably re-initialize it for every iteration through the retry loop.
