3.16.44-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Leon Romanovsky <leonro@xxxxxxxxxxxx>
commit 12bbf1ea7e3b35892dbb8636b978160bc9576b61 upstream.
In case of unsupported singature, we returned positive
value, while the better approach is to return -EINVAL.
In addition, in this change, the error print is enriched
to provide an actual supplied signature type.
