This patch turns a user mode driver error into a hard error, and updates
the relevant diagnostic slightly to help troubleshooting.  gphoto was
known to have this problem, hopefully it is now fixed (they have had
plenty of warning...)

This had been left as a soft error to give various user mode drivers a
change to be properly fixed, with the statement that starting in about
2.6.10 it would be changed.  It had been mostly safe as a soft error ...
but that can not be guaranteed.  Now that a year has passed, it's time to
really insist that the user mode drivers finally fix their relevant bugs.

Checking for NULL before calling kfree() is redundant. This patch removes
these redundant checks and also makes a few tiny whitespace changes.

I am sorry that the last patch about 32 bit compat ioctl on
64 bit kernel actually breaks the usbdevfs. That is on the current
BK tree. I am retarded. 

Here is the patch to fix it. Tested with USB hard disk and webcam
in both 32bit compatible mode and native 64bit mode.

Again, sorry about that.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
