Subject: [patch 11/14] Convert from class_device to device for USB host
--
Content-Disposition: inline; filename=usb-host.patch
Convert from class_device to device for drivers/ide/usb/host. 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be superceded by a diff mechanism.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. Thanks!
