Please make sure of the following things
CONFIG_ATH_COMMON=m
CONFIG_ATH_DEBUG=y

CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K=m
CONFIG_ATH9K_DEBUGFS=y
CONFIG_ATH9K_RATE_CONTROL=y
CONFIG_ATH9K_HTC=m
CONFIG_ATH9K_HTC_DEBUGFS=y

sudo modprobe ath9k debug=0xffffffff

you will get lot of messages from the debug log.
