Subject: [patch 10/14] Convert from class_device to device for USB core

-- 
Content-Disposition: inline; filename=usb-core.patch

Convert from class_device to device for drivers/ide/usb/core.   Greg, not
sure if you're looking for a patch for this. Kay mentioned maybe it was to
be superceded by a diff mechanism.  Free free to drop if so.
