2011-11-18USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman1-11/+1
This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.
