Hi,
Unlike other drivers, the pwc driver lies about its name in /proc/bus/devices and in /sys:
$ cat /proc/bus/usb/devices|fgrep Phil
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam
I:* If#= 0 Alt= 1 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam

I: If#= 0 Alt= 7 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam
I: If#= 0 Alt= 8 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam
I: If#= 0 Alt= 9 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam
I: If#= 0 Alt=10 #EPs= 2 Cls=ff(vend.) Sub=00 Prot=00 Driver=Philips webcam
This make harder for tools that rely on this to find out which driver
drive a piece of hardware. Such as Mandriva Linux tools.
The following patch fixes this:
