Subject: [PATCH 09/16] crypto: atmel-tdes - Drop unnecessary passing of tfm
Date: Thu, 5 Dec 2019 09:53:58 +0000 [thread overview]
Message-ID: <20191205095326.5094-10-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20191205095326.5094-1-tudor.ambarus@microchip.com>
From: Tudor Ambarus <tudor.ambarus@microchip.com>
atmel_tdes_crypt_start() obtained a pointer to tfm from dd,
passed the tfm pointer to atmel_tdes_crypt_{dma,pdc}, and in
the calles we obtained dd back from the tfm. Pass pointer to
dd directly.
