[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jimmy Assarsson <jimmyassarsson@xxxxxxxxx>

commit 8f65a923e6b628e187d5e791cf49393dd5e8c2f9 upstream.

If the return value from kvaser_usb_send_simple_msg() was non-zero, the
return value from kvaser_usb_flush_queue() was printed in the kernel
warning.
