Subject: [PATCH v0] Crypto: Talitos: re-initialize async_tx descriptors
Date: Mon, 14 Dec 2009 19:03:22 +0530 [thread overview]
Message-ID: <1260797602-7476-1-git-send-email-Vishnu@freescale.com> (raw)
The async_tx descriptors contains dangling pointers.
Hence, re-initialize them to NULL before use.
