The bug was caused by usbfs not unbinding from an interface when the USB device file was closed, which led another process to attempt the unbind later on, after the private data structure had been deallocated. The reason usbfs did not unbind the interface at the appropriate time was because it thought the interface had never been claimed in the first place. This was caused by the fact that usb_driver_claim_interface() does not clean up properly when device_bind_driver() returns an error. Although the error code gets passed back to the caller, the iface->dev.driver pointer remains set and iface->condition remains equal to USB_INTERFACE_BOUND. This patch adds proper error handling to usb_driver_claim_interface().

This patch removes the two LPM-related function calls from the routine. The reason for disabling LPM in the analogous function usb_probe_interface() is so that drivers won't have to deal with unwanted LPM transitions in their probe routine. But usb_driver_claim_interface() doesn't call the driver's probe routine (or any other callbacks), so that reason doesn't apply here. Furthermore, no driver other than usbfs will ever call usb_driver_claim_interface() unless it is already bound to another interface in the same device, which means disabling LPM here would be redundant. usbfs doesn't interact with LPM at all. Lastly, the error return from usb_unlocked_disable_lpm() isn't handled properly; the code doesn't clean up its earlier actions before returning.
