Subject: ath9k: fix misplaced debug code
X-Git-Tag: v2.6.39-rc1~468^2~448^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8d8d3fdc0d42be0ba75be227465773a54bb48a0b;p=platform%2Fkernel%2Flinux-exynos.git

ath9k: fix misplaced debug code

The commit 'ath9k: Add more information to debugfs xmit file.' added more
debug counters to ath9k and also added some lines of code to ath9k_hw.

Since ath9k_hw is also used by ath9k_htc, its code must not depend on ath9k
data structures. In this case it was not fatal, but it's still wrong, so
the code needs to be moved back to ath9k.
