Subject: [PATCH 08/14] crypto: inside-secure - unify cache reset
Date: Mon, 27 May 2019 16:51:00 +0200 [thread overview]
Message-ID: <20190527145106.8693-9-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20190527145106.8693-1-antoine.tenart@bootlin.com>
This patch unify the way the cache related data is zeroed when the cache
buffer is DMA unmapped. It should not change the driver behaviour, but
improves the code safety and readability.
