The ISO descriptors are allocated separately in proc_submiturb for a fetch
from user mode, then tucked at the end of URB. This seems like a dead code.

This patch (as1022b) adds stub methods for suspend and resume to the
usbfs driver.  There isn't much they can do since there's no way to
inform a user task about the events.  But it's important to have the
stubs, because an upcoming change to usbcore will automatically unbind
drivers that don't have those methods when a suspend occurs.

For as long as I've known about it, the USBDEVFS_CONNECT ioctl hasn't
done what it's supposed to.  The current code reprobes _all_ the
unbound USB interfaces; this patch (as1021) makes it reprobe only the
interface for which it was called.

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

This patch (as948) removes most of the references to urb->pipe from
the usbfs routines in devio.c.  The one tricky aspect is in
snoop_urb(), which can be called before the URB is submitted and which
uses usb_urb_dir_in().  For this to work properly, the URB's direction
flag must be set manually in proc_do_submiturb().

The patch also fixes a minor bug; the wValue, wIndex, and wLength
fields were snooped in proc_do_submiturb() without conversion from
le16 to CPU-byte-ordering.

struct cdev does not need the kobject name to be set, as it is never
used.  This patch fixes up the few places it is set.
