Subject: [PATCHv3] usb: core: Change usb_create_sysfs_intf_files()' return type to void
The usb_create_sysfs_intf_files() function always returned zero even
if it failed to create sysfs fails. Since this is a desired behaviour
there is no need to return return code at all. This commit changes
function's return type (form int) to void.
