From 175f88a374ca905293f67219a8201cd00a27f541 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 28 Mar 2017 10:33:15 +0200 Subject: USB: lvstest: tighten endpoint sanity check Use the new endpoint helpers to lookup the required interrupt-in endpoint. Note that this in fact both loosens and tightens the endpoint sanity check by accepting any interface with an interrupt-in endpoint rather than always using the first endpoint without verifying its type.
