From 6a1eaf19f525ed9e4fa09ed1f05c6502a90b4ccb Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 16 Mar 2017 17:13:46 +0100 Subject: [PATCH] USB: serial: mos7720: always require an interrupt endpoint This driver have treated the interrupt endpoint as optional despite it always being present (according to the datasheet). Let's consider it mandatory instead.
