From 65c35dd59002798cc87212d23ff3c87fd3a5d721 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 18 May 2015 17:34:12 +0200 Subject: [PATCH] USB: cdc-acm: add support for up to 256 devices Increase the minor range to enable support for up to 256 devices. Some people are hitting the current 32 device limit. Hopefully 256 minors will be enough for while still.
