Subject: [PATCH 04/14] crypto: inside-secure - remove useless check
Date: Mon, 27 May 2019 16:50:56 +0200 [thread overview]
Message-ID: <20190527145106.8693-5-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20190527145106.8693-1-antoine.tenart@bootlin.com>
When sending an ahash request, the code checks for the extra variable
not to be 0. This check is useless as the extra variable can't be 0 at
this point (it is checked on the line just before).
This patch does not modify the driver behaviour in any way.
