[PATCH] USB: ioctl compat for usblp.c
From: David Woodhouse <dwmw2>
David has a G5 with a printer. I am quite surprised that nobody else noticed
this before. Linus has a G5. Hackers hate printing in general, maybe.
We do not use BKL anymore, because one of code paths had a sleeping call,
so we had to use a semaphore. I am sure it's safe to use unlocked_ioctl.
The new ioctls return long and retval is int. It looks completely fine to me.
We never want these extra bits, and the sign extension ought to work right.
