From 1c5176692457c3f249559d29a69affad7447b326 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 25 Apr 2012 15:56:30 +0200 Subject: [PATCH] USB: oti6858: fix abuse of interface data Fix abuse of interface data which was used to signal device disconnect. Note that neither tiocmset or tiocmget need to check for disconnect as they do not access the device.
