From ae75c940181c3d4044f7b1adf07ada877ad9cb83 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 26 May 2014 19:23:24 +0200 Subject: [PATCH] USB: usb_wwan: kill interrupt urb explicitly at suspend As the port interrupt URB is submitted by the subdriver at open, we should also kill it explicitly at suspend (even though this will be taken care of by USB serial core otherwise).
