| |
2.6.34-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sujith <Sujith.Manoharan@atheros.com>
commit 736b3a27b3c50c4a23717b802240435a69e8d0ff upstream.
Without this you will get a panic if the device initialization fails. Also, free ath_hw instance properly. ath9k_hw_deinit() shouldn't do it.
