Along with all of the other comments from people, I have a few.

No, please create 1 patch per type-of-change.

So in this case you would have a series of patches:
1) add the class iterator functions
2-n) convert the existing places in the kernel using the
class->semaphore to use the new iterator functions
n+1) convert class semaphore to mutex, which should only touch
the driver core

That way everything builds along the way, and it's easy to understand
and review.

Oh, and please start a new thread when you create a new patch like this
so it doesn't get burried in people's inboxes...

thanks,
