Fix up the documentation. Apparently, I left unedited copy-paste results
in examples. Also, Alan helped me to improve the most confusing parts.

Some usbserial functions returns -EINVAL if the port doesn't exist or if
it's not opened. However, the right error code for such situations is
-ENODEV.

Hi there.
While porting the ftdi_sio driver to the new USB-Serial, I faced a problem
I think we'll have with other drivers as well.
The problem is that ftdi_sio calls usb_control_msg() in ftdi_tiocmget()
to get the modem status from the device, but ftdi_get_mctrl() (Serial
Core version) canno

This patch (as719) ties together the states of devices and their
interfaces: No longer is it possible to suspend one without also
suspending the other. The states that are ruled out (some interfaces
suspended, entire device still awake) don't seem to be very useful, at
least not for now.

Greg:
This patch (as718) includes a large cleanup of the suspend/resume code in
usbcore. The most notable change is the addition of a new field to the
usb_interface structure, for keeping track of whether the interface is
active or suspended. The intf->dev.power.power_state.event field can't
Greg:
This patch (as717) gets rid of the recursion we've always had in the
suspend and resume routines. Now suspending a hub won't automatically
suspend all the child devices first, and resuming a hub won't
automatically resume all the child devices afterward.
This is how other parts of the k
Greg:
This patch (as716) splits the core suspend/resume routines up into two
pieces, one for handling devices and one for handling interfaces. This is
a lot cleaner than doing both in one routine.

This patch (as713) moves a few driver-related routines from one source

This patch (as712) fixes the usb-skeleton example driver so that it won't
try to submit URBs after skel_disconnect() has returned. This could cause
errors, if the driver was unbound and then a different driver was bound to
the device.
The patch also fixes a couple of small bugs in the skel
Greg:
This patch (as711) modifies the usbfs code to detect when a device has
been unregistered from usbfs, even if the device is still connected.
Although this can't happen now, it will be able to happen after an
upcoming patch.

Greg and everyone else:
The following patches form a general clean-up and reorganization of the
suspend/resume support in usbcore. I developed them in the course of
working on autosuspend and autoresume. That work isn't finished yet, but
it still seemed like a good idea to submit these first bec
