Ah fuck, Joe's patch got in *later* and it did not address changing
dfs.c. I had raised this as a comment to Joe's patch while we had
pending patches. It seems this is collateral damage or roadkill.

commit d2182b69dcb6a68b1ef6070b2efd094e13dea3f1
Author: Joe Perches <joe@...ches.com>
Date:   Thu Dec 15 14:55:53 2011 -0800

    ath: Convert ath_dbg(bar, ATH_DBG_<FOO>, to ath_dbg(bar, FOO

    Add ATH_DBG_ to macros to shorten the uses and
    reduce the line count.

    Coalesce ath_dbg formats.
    Add missing spaces to coalesced formats.
    Add missing newline terminations to ath_dbg formats.
    Align ath_dbg arguments where appropriate.
    Standardize ath_dbg formats without periods.

Sorry for the trouble but the fix is trivial, I'll sumbit shortly.
