From a7fa57742ea692631a4076254408366a01eb3582 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 21 Mar 2013 12:37:04 +0100 Subject: [PATCH] USB: digi_acceleport: remove unused MSR-wait queue Remove unused, private modem-status wait queue from driver. If TIOCMIWAIT is ever implemented it must not rely on a private wait queue which may have been released when woken up.
