Subject: [PATCH 1/8] cryptoloop: fix a sparse annotation
Date: Thu, 26 Aug 2021 15:38:03 +0200 [thread overview]
Message-ID: <20210826133810.3700-2-hch@lst.de> (raw)
In-Reply-To: <20210826133810.3700-1-hch@lst.de>
iv is used as a little endian value, so use a __le32 type for it. Also
move the initialization into the declaration to simplify it a bit.
