From 964ee1deb3eac802902cd758ddb94b6a95c77987 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 17 Oct 2006 10:17:58 -0700 Subject: [PATCH] USB: cleanup sierra wireless driver a bit This saves over 30 lines and fixes a warning from sparse and allows debugging to work dynamically like all other usb-serial drivers.
