Subject: [PATCH V9 02/13] powerpc, perf: Change type of the bhrb_users variable
Date: Mon, 15 Jun 2015 17:40:57 +0530 [thread overview]
Message-ID: <1434370268-19056-3-git-send-email-khandual@linux.vnet.ibm.com> (raw)
In-Reply-To: <1434370268-19056-1-git-send-email-khandual@linux.vnet.ibm.com>
This patch just changes data type of bhrb_users variable from
int to unsigned int because it never contains a negative value.
Reported-by: Daniel Axtens <dja@axtens.net>
Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com>
