Perfect.

I ended up applying my earlier cleanup patch with just the added
removal of the kfree(), which was the actual trigger of the bug.

It's commit e423fb6929d4 ("driver code: clarify and fix platform
device DMA mask allocation") in my tree. I've not pushed it out yet (I
have a few pending pull requests), but it should be out shortly.
