Well, it's not required, but it is nice to have.  I didn't merge the
"convert the driver core semaphore to a mutex" patch as it was causing
too many false-positive lockdep warnings.

Hopefully the lockdep core will be tweaked to handle the locking tree
that the device core requires and then when that happens, I will merge
the patch that will require this fix in order to keep the build from
breaking.

But for now, it's not a requirement, although, it does make my life
easier.

thanks,
