Subject: [PATCH V3 12/15] ARM: vexpress: cleanup cppcheck shifting error
Date:   Tue, 25 Jun 2019 11:03:53 +0700
Message-Id: <20190625040356.27473-13-tranmanphong@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

There is error from cppcheck tool
"Shifting signed 32-bit value by 31 bits is undefined behaviour errors"
change to use BIT() marco for improvement.
