A linked list isn't very nice either. Try using idr, which gives you
both an allocator for the minor number space, and a way to look up
the structure by that index.

This section should be in the main commit log, and not that part with
the changelog which gets dropped.

Please don't use global variables with generic names. In this case you
should neither make it global nor give it a generic name.
