you moved this part in laste patch from spectralscan.h to ath9k.h. If
you wont to move it other place you should do it in previous patch.

1. This patch should not include HTC related changes. You should just
move code without changing it. Think about people who need to fix it if
some thing went wrong with this patch set.
2. Use linux/scripts/checkpatch.pl before sending patch for review. It
will save time you and me ;)
