Hi!
Here's a patch for the Philips Webcam Driver.
I had a problem for a while where an application freezed (never got out of
ioctl) when someone pulled the plug on the camera.
Now for me the problem is solved.
(I don't hold a copy of a whole kernel, so i just copyed the file and made a
diff of my current kernel (2.4.16), but the change is trivial...)
