From fd0c883e597493d85d0800629798fc6fcce8e24e Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 2 Mar 2017 12:51:23 +0100 Subject: [PATCH] USB: serial: io_edgeport: simplify and tighten endpoint check Simplify the endpoint sanity check by letting core verify that the required endpoints are present. Also require the presence of a bulk-out endpoint, something which prevents the driver from trying to send bulk messages over the control pipe should a bulk-out endpoint be missing.
