I found a DLink DWM 652 U5 USB 3G modem has product ID 0xce1e instead
of orignal 0xce16. The new ID is added.

And I found there are two entries for 0xce16, one has raw number, the
other has symbol DLINK_PRODUCT_DWM_652_U5. This is fixed too.

Longcheer is a Chinese company that manufactures the devices which a
bunch of different companies like Alcatel, 4G Systems, and Mobidata
rebrand.  While I can't find Longcheer's USB ID registered anywhere,
it's pretty clear the ID is theirs.

This patch (as1344) removes references to port->port.count from the
USB serial drivers.  Now that serial ports are properly reference
counted, port.count checking is unnecessary and incorrect.  Drivers
should assume that the port is in use from the time the open method
runs until the close method is called.

The 4G XS Stick W14 seems to not understand RTS/DTR setting in
option_send_setup causing long timeouts on any open() which disturbs a
lot of well-known userspace applications like minicom or ModemManager.

Therefore, we enable OPTION_BLACKLIST_SENDSETUP blacklisting for it.

As suggested by Matthias Urlichs, this patch adds a somehow generic
mechanism for special handling of devices which don't support all bits
expected by this driver.

The blacklisting code is heavily stolen from sierra.c, but extended to
support different special cases.

For now, one case is implemented (OPTION_BLACKLIST_SENDSETUP), targeted
at the 4G W14 device: devices which don't understand the setting of
RTS/DTR in option_send_setup() causing a USB timeout of 5 s in any
userspace open() which leads to errors in most userspace applications.

In addition, I prepared another case for devices with interfaces which
shall not be accessed by this driver (targeted at the D-Link DWM 652).

However, OPTION_BLACKLIST_RESERVED_IF is not fully implemented yet as I
have no device to test this. Anyone volunteering to help here?  If not,
I'll contact the guys who added D-Link DWM 652 support soon.

This patch (as1264) removes a bunch of unnecessary and erroneous stuff
from the option USB-serial driver.  Clearly there's no need to verify
that the device pointer stored in the URBs is right or to store the
same pointer over again.  After all, the pointer can't change once it
has been set up.

There's also no need to call usb_clear_halt for the IN endpoint
multiple times -- in fact, doing so is an error since every time after
the first there will be active URBs queued for that endpoint.  Since
the Clear-Halts don't appear to be needed at all, the patch simply
removes them.

This patch (as1254) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.
