Subject: [char-misc 4.3] mei: hbm: fix error in state check logic
Date: Sun, 13 Sep 2015 10:29:26 +0300 [thread overview]
Message-ID: <1442129366-13061-1-git-send-email-tomas.winkler@intel.com> (raw)
From: Alexander Usyskin <alexander.usyskin@intel.com>
Use || instead && in state check.
Latter is bogus and leads to following warning:
drivers/misc/mei/hbm.c:1212:46: warning: logical ‘and’ of mutually exclusive tests is always false [-Wlogical-op]
Fixes: 073e6274 ("mei: support for dynamic clients")
Reported-by: David Binderman <dcb314@hotmail.com>
