From 90246e79af062fcbb8c3728a5f29cb19b3468f59 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 4 Nov 2010 13:00:22 -0500 Subject: crypto: hash - Fix async import on shash algorithm The function shash_async_import did not initialise the descriptor correctly prior to calling the underlying shash import function. This patch adds the required initialisation.
