Subject: [PATCH 4.4 31/46] USB: ldusb: fix control-message timeout

From: Johan Hovold <johan@...nel.org>

commit 52403cfbc635d28195167618690595013776ebde upstream.

USB control-message timeouts are specified in milliseconds, not jiffies.
Waiting 83 minutes for a transfer to complete is a bit excessive.

Fixes: 2824bd250f0b ("[PATCH] USB: add ldusb driver")
