usbatm: create sysfs link "device" from atm class device to usb interface
There is currently no path from the ATM device in /sys to the USB device's
interface that the driver is using; this patch creates a "device" symlink. It
is then possible to get to the cxacru ADSL statistics
(http://lkml.org/lkml/2007/2/23/328):
/sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation
downstream_attenuation downstream_snr_margin upstream_rate
downstream_rate upstream_attenuation upstream_snr_margin
If this link is not appropriate I'd have to create device files in
/sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL
statistics are for the USB device not ATM (which is running over the ADSL).
