[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.
