Subject: [PATCH] powerpc/xmon/ppc-opc: Use ARRAY_SIZE macro
Message-ID: <20181004171036.GA1907@embeddedor.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.5.24 (2015-08-30)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element.

This code was detected with the help of Coccinelle.
