[PATCH] USB core and HCDs: don't put_device while atomic
This patch (as640) removes several put_device and the corresponding get_device calls from the USB core and HCDs. Some of the puts were done in atomic contexts, and none of them are needed since the core now guarantees that every endpoint will be disabled and every URB completed before a USB device is released.
