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

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

From: Thomas Zimmermann <tzimmermann@xxxxxxx>

[ Upstream commit 2c1eafc40e53312864bf2fdccb55052dcbd9e8b2 ]

Set the USB control-message timeout to the USB default of 5 seconds.
Done for consistency with other uses of usb_control_msg() in udl and
other drivers.
