Subject: crypto: cavium - fix leak on curr if curr->head fails to be allocated
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d80388eca1b476125755a811676f76f138bbbe28;p=openwrt%2Fstaging%2Fblogic.git

crypto: cavium - fix leak on curr if curr->head fails to be allocated

The exit path when curr->head cannot be allocated fails to kfree the
earlier allocated curr.  Fix this by kfree'ing it.
