Subject: [PATCH v4 7/8] sym53c8xx_2: Convert to use memset32
Date: Thu, 20 Jul 2017 11:45:38 -0700 [thread overview]
Message-ID: <20170720184539.31609-8-willy@infradead.org> (raw)
In-Reply-To: <20170720184539.31609-1-willy@infradead.org>
From: Matthew Wilcox <mawilcox@microsoft.com>
memset32() can be used to initialise these three arrays. Minor code
footprint reduction.
