This is not a random stylistic change. My patch changes the way iface is
calculated. Therefore, removing an unnecessary pre-initialization of iface is
both obvious and expected.
The "iface = 0" line is used in the original code because the driver did not
have a "default" case for the "switch" statement. Since I added a default case,
there was no need to pre-initialize iface anymore.
If I had left that line in the driver, someone would have complained that I'm
pre-initializing iface unnecessarily.

Ok, so that means that you need to look at the original code in order to
understand the change completely. What's wrong with that? I just don't see how
this is a valid criticism for any patch.

Again, I just don't understand this complaint of my patch. I've carefully read
your email, and I re-examined my patch and the original code, and I still don't
think that there's anything wrong with the patch.
