-stable review patch. If anyone has any objections, please let us know.
------------------
From: Thomas Graf <[email protected]>
"return -err" and blindly inheriting the error code in the netlink
failure exception handler causes errors codes to be returned as
positive value therefore making them being ignored by the caller.
May lead to sending out incomplete netlink messages.
