Hello all,
ath5k will immediately crash when issuing the following command:

echo 2>  /sys/class/ieee80211/phy0/device/ani/ani_mode

The crash log looks like this:

[   66.425365] BUG: unable to handle kernel NULL pointer dereference at 00000100
[   66.425652] IP: [<e08e3008>] ath5k_ani_init+0xe/0x399 [ath5k]

It looks like we have a major bug in the ath5k sysfs code!  drvdata is 
set to hw as it should, but the sysfs code assumes it's set to sc.  I'm 
testing a patch now.
