USB: uss720: add debug endpoint-type check
Use the new endpoint helpers to lookup the interrupt-in endpoint, and only print the corresponding debugging information in case it is found. Note that the descriptors are searched in reverse order to avoid any regressions. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
