[PATCH] USB: PWC 9.0.1 

Attached you will find patches that will bring the PWC driver in the kernel
up to version 9.0.1 from 8.12 (9.0 wasn't accepted at first). Patches are
against 2.4.26 and 2.6.7. The main difference with 9.0 is that the
video_relase() routine is now hopefully in line with kernel requirements.
I've also added one more ioctl() call, upon request.

I'm also slightly in the dark on the status of the PWC in the 2.6 kernel;
I've seen two patches: the first was a bad one, since it would crash your
kernel when you unplug the cam. I've seen a second patch to reverse the
first one, but I don't know if that went in. Either way, you might get a
conflict in pwc-if.c in and about the pwc_video_release() routine; this
patch was generated against the clean 2.6.7 kernel source. Should you need
or want to fix it manually, this patch should remove the
pwc_video_release() in the 2.6 kernel.
