ath9k doesn't check (and eventually swap) the endianness of caldata if platform_data is set.
In my platform I have the caldata in flash (hence platform_data is set) but I need ath9k to swap the bytes, so I added a field to platform_data to force the check. Maybe there's a better way, but since nobody replied when I asked, I did it this way. Note that the method described in http://wiki.openwrt.org/doc/devel/patches doesn't seem to work with mac80211, so I had to do the patch manually.
