From: Johan Hovold Date: Thu, 21 Mar 2013 11:37:11 +0000 (+0100) Subject: USB: iuu_phoenix: remove unused MSR-wait queue X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=09b0e3957549e7036a66e4597a7167e43861cfd6;p=openwrt%2Fstaging%2Fblogic.git USB: iuu_phoenix: 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.
