[PATCH] usbcore: Improve endpoint sysfs file handling
This revised patch (as587b) improves the implementation of USB endpoint sysfs files. Instead of storing a whole bunch of attributes for every single endpoint, each endpoint now gets its own kobject and they can share a static list of attributes. The number of extra fields added to struct usb_host_endpoint has been reduced from 4 to 1. The bEndpointAddress field is retained even though it is redundant (it repeats the same information as the attributes' directory name). The code avoids calling kobject_register, to prevent generating unwanted hotplug events. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
