The EHCI driver stores in usb_host_endpoint.hcpriv a pointer to either
an ehci_qh or an ehci_iso_stream structure, and uses the contents of the
hw_info1 field to distinguish the two cases.

After ehci_qh was split into hw and sw parts, ehci_iso_stream must also
be adjusted so that it again looks like an ehci_qh structure.

This fixes a NULL pointer access in ehci_endpoint_disable() when it
tries to access qh->hw->hw_info1.

When isochronous URBs are shorter than one frame and when more than one
ITD in a frame has been completed before the interrupt can be handled,
scan_periodic() completes the URBs in the order in which they are found
in the descriptor list.  Therefore, the descriptor list must contain the
ITDs in the correct order, i.e., a new ITD must be linked in after any
previous ITDs of the same endpoint.

This should fix garbled capture data in the USB audio drivers.

It is possible to have a multi-port device with a port lacking an in or
out bulk endpoint. Only checking for num_bulk_in or num_bulk_out is thus not
sufficient to determine whether a specific port has an in or out bulk
endpoint.

This fixes potential null pointer dereferences in the generic open and
write routines, as well as access to uninitialised fifo in write_room
and chars_in_buffer.

Also let write fail with ENODEV (instead of 0) on missing out endpoint
(also on zero-length writes).

In the future, we are going to be changing the lock type for struct
device (once we get the lockdep infrastructure properly worked out)  To
make that changeover easier, and to possibly burry the lock in a
different part of struct device, let's create some functions to lock and
unlock a device so that no out-of-core code needs to be changed in the
future.

This patch creates the device_lock/unlock/trylock() functions, and
converts all in-tree users to them.

The caller of usbfs_conn_disc_event() in some cases (but not always)
already holds usbfs_mutex, so trying to protect the event counter with
that lock causes nasty deadlocks.

The problem was introduced by commit 554f7696 ("USB: Remove BKL from
poll()") when the BLK protection was turned into using the mutex instead.

So fix this by using an atomic variable instead.  And while we're at it,
get rid of the atrocious naming of said variable and the waitqueue it is
associated with.

This also cleans up the unnecessary locking in the poll routine, since
the whole point of how the pollwait table works is that you can just add
yourself to the waiting list, and then check the condition you're
waiting for afterwards - avoiding all races.

It also gets rid of the unnecessary dynamic allocation of the device
status that just contained a single word.  We should use f_version for
this, as Dmitry Torokhov points out.  That simplifies everything
further.

Many Qualcomm-based devices provide a CDC-ACM port which accepts
normal AT commands and PPP connections.  But they only provide one
which makes status or signal strength requests impossible while
PPP is active.  They also provide secondary USB interfaces that
talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be
used for status and strength.  Make those QCDM ports accessible.

I've got a trivial patch for the pl2303 driver, that's what I needed to
make the wacom serial tablet driver work properly. It uses the
TIOCGSERIAL ioctl to determine if it's talking to a serial device or
not, which I gather is rather common, but the pl2303 driver didn't
implement that ioctl.

While looping over the interfaces, if usb_hcd_alloc_bandwidth() fails it calls
hcd->driver->reset_bandwidth(), so there was no need to reinstate the interface
again.

If no break occurred, the index equals config->desc.bNumInterfaces. A
subsequent usb_control_msg() failure resulted in a read from
config->interface[config->desc.bNumInterfaces] at label reset_old_alts.

In either case the last interface should be skipped.
