Fix for ftdi_set_termios() glitching output
ftdi_set_termios() is constantly setting the baud rate, data bits and parity
unnecessarily on every call, . When called while characters are being
transmitted can cause the FTDI chip to corrupt the serial port bit stream
output by stalling the output half a bit during the output of a character.
Simple fix by skipping this setting if the baud rate/data bits/parity are
unchanged.

commit 0c16595539 upstream.
I get report from customer that his usb-serial
converter doesn't work well,it sometimes work,
but sometimes it doesn't.
The usb-serial converter's id:
vendor_id product_id
0x4348 0x5523
Then I search the usb-serial codes, and there are
two drivers announce support this device, pl2303
and ch341, commit 026dfaf1 cause it. Through many
times to test, ch341 works well with this device,
and pl2303 doesn't work quite often(it just work quite little).
ch341 works well with this device, so we doesn't
need pl2303 to support.I try to revert 026dfaf1 first,
but it failed. So I prepare this patch by hand to revert it.

The funtion option_send_status times out when sending USB messages

This patch adds a blacklist entry for these 3 interfaces on the ZTE

This modem really wants sendsetup blacklisted for interfaces 0 and 1,
otherwise the kernel hardlocks for about 10 seconds while waiting for
the modem's firmware to respond, which it of course doesn't do.
A slight complication here is that TCT (who owns the Alcatel brand) used
the same USB IDs for the X200 as the X060s despite the devices having
completely different firmware and AT command sets, so we end up adding
the X060s to the blacklist at the same time. PSA to OEMs: don't use the
same USB IDs for different devices. Really. It makes your kittens cry.

I am sharing patch to the devices/usb/serial/option.c. This allows
operation of Huawei E353 broadband modem using the “option” driver. The
patch simply adds new constant with proper product ID and an entry to
usb_device_id. I worked on the 2.6.38.6 sources. Tested on Dell inspiron
1764 (i3 core cpu) and brand new Huawei E353 modem, Fedora 15 beta.
Looking at the type of change, i doubt it has potential to introduce
problems in other parts of kernel or the driver itself.

This reverts commit 90593899de.
SAM-BA devices identify themselves CDC-ACM devices and should be using
the cdc-acm driver.
Since commit 5b239f0aeb (USB: cdc-acm: Add pseudo
modem without AT command capabilities) cdc-acm also binds to them.
Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus
require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be
able to select the device. This is simply a UI-issue that should be
fixed by Atmel.
Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek.
