Ok, FUJITA Tomonori, please make sure a patch like the following goes
into the same trees that you submitted commit 353c409 to.
Also make sure to check b43legacy. I _guess_ you might have added
the same bug there.
Ah, sorry about the bug.

From a quick look, mainline needs the same fix too?

b43_dma_mapping_error calls unmap_descbuffer() on the failure, which
assumes that ring->dev is set up properly.

Yeah ok. That's an unlikely error path.
The new bug is in the main path which will always trigger.

Next time please send _any_ patch for review to me and to the wireless list.
Please tell me which trees this bug has been merged to. Is it already in
Linus' tree?

The equivalent line in Linus's tree is "if (unlikely(dma_mapping_error(addr)))", thus the error has not reached mainline (yet?).
