Hm, looks like some of the patches need to be revised because
.owner is already set in the ops, and a warning gets generated.

Also it'd be good to mention why Johannes's approach was abandoned.

When you repost please separate out all the patches for
drivers/net/wireless/ and send that to Kalle's wireless drivers tree.
Patch 1 needs to be split in two. Patches 2 and 3 would go via Johannes.
The wimax patch needs to go to staging (wimax code has been moved).
The remaining patches can be posted individually, not as a series.
