This patch is the result of that discussion a short while back to fix the "hub driver polls too quickly at high speed" bug.
- redefines "interval" of usb_fill_int_urb() to be what
the endpoint descriptor returns, and transparently
does the log-to-linear conversion if it's high speed
- (most of the patch by volume!!) moves declarations
forward so testing dev->speed there will compile.
No driver changes were needed -- most drivers pass the
endpoint bInterval value already, and those that don't are
not dealing with high speed device quirks.

p.s. Includes an unrelated one-liner: deletes export of
usb_inc_dev_use() so it now shows up in kernel doc.
Minor oversight in an earlier patch.
p.p.s. Driver-visible API change in 2.5.10: if you use
fops, you MUST set num_minors ... listing in the
/proc/bus/usb/drivers file happens even if there's
no way the driver will be accessible. I think it'd be
better to fail the registration if num_minors is zero
for a driver using fops.
