Date: Fri, 22 Apr 2016 14:15:22 +0200 From: Krzysztof Kozlowski <k.kozlowski@...sung.com> To: Herbert Xu <herbert@...dor.apana.org.au>, "David S. Miller" <davem@...emloft.net>, linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Vladimir Zapolskiy <vz@...ia.com>, Krzysztof Kozlowski <k.kozlowski@...sung.com>, Bartlomiej Zolnierkiewicz <b.zolnierkie@...sung.com> Subject: [PATCH 1/2] crypto: s5p-sss - Use common BIT macro The BIT() macro is obvious and well known, so prefer to use it instead of crafted own macro.
