Subject: [PATCH] w35und: usb_put_dev() is missing from wb35_disconnect()

From: Pekka Enberg <penberg@...helsinki.fi>

The wb35_probe() function does usb_get_dev() so add a missing usb_put_dev() to
the wb35_disconnect() function. Also fix error handling paths in wb35_probe()
to call usb_put_dev() as well.
