According to Jonas Fährmann, the very first entry in unusual_devs.h isn't
needed.  In fact, I can't tell why it was there in the first place...
unless some earlier device in the product line had incorrect descriptor
values.

This patch adds support for the FTDI FT2232C USB to dual serial port
converter to the ftdi_sio driver.

The patch is based on a fork of the 2.4 ftdi_sio driver by Steven
Turner of FTDI, and a preliminary port of these changes to the 2.6
ftdi_sio driver by Rus V. Brushkoff.  I've tidied it up and fixed a
couple of things.

I don't have a FT2232C to test it with, but Steven Turner of FTDI
has tested it.  He mentioned a couple of known problems with the
driver, but nothing to do with this patch.

I've dredged up another old ftdi_sio patch that I never Cc'd to you
the first time.  Please see Nathan's description below.

It applies okay against your usb-2.6 tree, with or without the patch
I posted yesterday to support the FT2232C chip and neither patch
invalidates the other in any way.

Nathan's email suffered from a line-folding bug (blame M$,
probably!), so his patch came out corrupted. I'm reposting an

The following patch is in use by REINER-SCT customres for some time and
works for them in about 90% of all cases.  I would really appreciate
this going in before 2.6.8-final, since the device doesn't work at all
with current 2.6.x driver.

Changes:
- bump version number
- open interrupt endpoint in startup() rather than open

Please merge; the CONFIG_USB_SUSPEND patch depends on it.

This hub patch:

 - updates internal docs about locking, matching current usage
   for device state spinlock and dev->serialize semaphore

 - adds locktree() to use with signaling that affect everything
   downstream of a given device ... right now just khubd uses it,
   but usb_reset_device() should too (not just with hub resets...)

 - adds hub_quiesce()/hub_reactivate() ... former is used now
   during shutdown, both are needed in suspend/resume paths

Net change in behavior for current systems should be nothing.

This is the core of the USB_SUSPEND functionality.  Please merge.

This adds an experimental CONFIG_USB_SUSPEND option, which supports the
USB "suspend" state.  Linux-USB hosts have previously ignored that state.

    -	New driver API calls, usb_suspend_device() and its
	sibling usb_resume_device().

    -	Access to those calls through sysfs, such as
		echo -n 2 > power/state
		echo -n 0 > power/state

That can be used to reduce the power consumption of any given USB device,
then re-activate it later.  Eventually, most USB device drivers should
probably suspend idle USB devices.

One problem with this patch:  USB drivers without suspend() callbacks
may badly misbehave.  Right now only hub drivers know suspend().  If the
driver core didn't self-deadlock when we try it, unbinding those drivers
from those devices (then re-enumerating on resume) would be perfect...
the current compromise is just to emit a warning message.

In conjunction with host controller driver support (already merged for
OHCI and EHCI), PCI host controllers will issue the PME# wakeup signal
when a USB keyboard starts remote wakeup signaling.  (But the keyboard
wasn't usable later, since HID doesn't try to suspend.)

I understand some ACPI patches are circulating, and maybe already in
the MM tree, to make a suspended system wake up given PME# signaling.
It'd be great if someone made that work transparently with USB, but
for now I'm told it'll need some sysfs setup first.

This patch follows the suggestions sent by Todd Fischer and Diego Dompe
for making removable-LUN support part of the normal non-testing version of
the g_file_storage driver.  It also moves LUN device registration to the
correct place and eliminates a code path that stalls the bulk-out pipe in
a racy way.

There are also some smaller changes: update some comments, add initial
debugging support for USB suspend/resume, and miscellaneous code cleanups.
Last but not least, the driver has been sufficiently stable for
sufficiently long that it's fair to remove the "(DEVELOPMENT)" warning in
Kconfig.

This patch fixes a NULL-pointer-dereference bug in the dummy_hcd driver.
It also makes the code slightly more elegant and removes an unnecessary
buffer-overflow test.  Unfortunately it's still a little bit racy, but
this is a fault it shares with other gadget controller drivers, like
net2280.

con_font_set() sanitized.  We are passing console_font and flags into
the method in separate arguments and we are not messing with
console_font_op->data anymore - it's a userland pointer (to be annotated
several patches later in the series, due to another abuse of console_font_op
that needs to be fixed first), while console_font->data is kernel one
and they don't mix anymore.

We also do a sanity check (font width > 0) in the caller instead of
method instances, since we are already checking for width <= 32 and
height <= 32 there; doesn't make sense leaving that one in method
instances.

->con_font_copy() sanitized.  We extract the number of console to copy the
font from in the caller (it's taken from the field of console_font_op that
is normally used for font height - messy even for an ioctl, but that animal
used to be passed all the way down into console drivers).

With decoding done in con_font_copy(), we simply pass source console number
into the method.

Preparations for cleanups: con_font_op() is turned into a switch calling
con_font_{get,set,default,copy} depending on the operation required;
method ->con_font_op() also split, with NULL resulting in -ENOSYS on
operation in question.

Code that used to be in con_font_op() got slightly cleaned up after move
into new helpers (we are beginning to untangle the mess; there will be
more cleanups in the next patches).

Methods are currently using exact same arguments as old ->con_font_op().
That will change in subsequent patches, method by method (right now there's
a hell of a scary field reuse between them, making impossible to do any
static checks and practically begging for bugs).
