Subject: [PATCH] iscsi-target: Make buf param of iscsit_do_crypto_hash_buf() const void *
Date: Fri,  3 May 2013 23:15:57 +0200	[thread overview]
Message-ID: <1367615757-1447-1-git-send-email-geert@linux-m68k.org> (raw)

Make the "buf" input param of iscsit_do_crypto_hash_buf() "const void *".
This allows to remove lots of casts in its callers.
