3.13.11-ckt30 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Russell King <rmk+kernel@arm.linux.org.uk> commit 8996eafdcbad149ac0f772fb1649fbb75c482a6a upstream. Unlike shash algorithms, ahash drivers must implement export and import as their descriptors may contain hardware state and cannot be exported as is. Unfortunately some ahash drivers did not provide them and end up causing crashes with algif_hash. This patch adds a check to prevent these drivers from registering ahash algorithms until they are fixed.
