Subject: crypto: sahara - pass on error condition
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6cf02fcab1f6158c224fb00619f21556d8e5c4ea;p=openwrt%2Fstaging%2Fblogic.git

crypto: sahara - pass on error condition

A failure of sahara_hw_descriptor_create() with -EINVAL due to scatter list
out of bounds/invalid would not be reported back. This patch just passes on
the -EINVAL so it is visible in sahara_queue_manage().
