USB: sierra driver - add update dtr logic
The following improvements were made: - Fixed control line issue where asserting DTR on ep5 would close ep2 - Added support for calc_num_ports (will help support future composite devices) Signed-off-by: Kevin Lloyd <linux@sierrawireless.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
