The device setup did miss to initialize the num_interrupt_out field, thus
failing to successfully complete the probe function.

commit 04d06ad0f1 have added menuconfig support
for the whole USB Kconfig, but there are still menuconfig need for usb/serial,
usb/atm, and usb/gadget, so that the user can disable all the options in that
menu at once instead of having to disable each option separately.

these drivers abused intfdata in close() as flags for binding.
That races with reprobing of those devices. This patch fixes that by using

If disconnect() is called for a logical disconnect, no more IO must be
done after disconnect() returns, or the old and new drivers may conflict.
This patch avoids this by using the flag and lock introduced by the earlier
patch for the mos7720 driver.

this driver uses usb_get_intfdata() == NULL as a test for disconnect().
You must not do that as this races with probe(). By the time you test
your erstwhile interface may already be somebody else's interface.
This fixes the close() method of cypress_m8 to use the recently introduced
flag and use locking against disconnect() where required in close().

This fixes a problem where the mos7720 driver will make io to a device from
which it has been logically disconnected. It does so by introducing a flag by
which the generic usb serial code can signal the subdrivers their
disconnection and appropriate locking.

When building an external module, the ezusb_* functions are not defined

[PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors
There are more devices similar to the Olimex JTAG adaptor, in that the first
port of the FT2232C is used for JTAG, and only the second port is available as
UART.
I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and
added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the
OOCDlink device.
I've also updated the KERN_INFO message sent to userspace to remove the word
'olimex' and an extra '\n' that was causing an empty line in dmesg.

The check for NULL is bogus. This patch removes the check.

Without this fix, the pl2303 usb-serial adapter would not suspend properly
unless it had been opened first. A pl2303 type_1 chip will still break if the
system is hibernated while the RS-232 connector is powered by another system.
This was broken before, and a reset resume does not fix it. All other suspend
and autosuspend scenarios work with ATEN pl2303 adaptors with HX and type_1 chips.
