Hi,
my Huawei 3G modem has an embedded Smart Card reader which causes
trouble when the modem is being detected (a bunch of "<warn> (ttyUSBx):
open blocked by driver for more than 7 seconds!" in messages.log). This
trivial patch corrects the problem for me. The modem identifies itself
as "12d1:1406 Huawei Technologies Co., Ltd. E1750" in lsusb although the
description on the body says "Model E173u-1"

commit 6c1ee66a0b upstream.
This fixes an issue where the bulk-in urb used for incoming data transfer
is not resubmitted if the packet recieved contains an error status. This
results in the driver locking until the port is closed and re-opened.

commit ef6c8c1d73 upstream.
The parallel-port code of the drivers used a stack allocated

Per some ZTE Linux drivers I found for the AC2716, the following patch
moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff
that option does is not required with zte_ev, because it doesn't
implement any of the send_setup hooks which the blacklist suppressed.
I did not move the 2718 over because I could not find any ZTE Linux
drivers for that device, nor even any Windows drivers.
