From aa61556fa3cf7d0e39a67dc5b043b96519ce3726 Mon Sep 17 00:00:00 2001 From: Joe Carnuccio Date: Thu, 9 Feb 2012 11:15:40 -0800 Subject: [PATCH] [SCSI] qla2xxx: Return blank sysfs string on initial get thermal failure. When thermal temperature initially fails, return a blank string to the sysfs interface. This fixes the initial display of 0.00 followed by subsequent display of blank line; the initial 0.00 should have not displayed for cards that do not support thermal temperature.
