Missinng dependency for debugfs in driver ath9k

Hello i have problem with making your driver in linux kernel:

psix linux # LANG=C make -j5
make[1]: Nothing to be done for `all'.
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
make[1]: Nothing to be done for `relocs'.
CALL scripts/checksyscalls.sh
<stdin>:1223:2: warning: #warning syscall finit_module not implemented [-Wcpp]
CHK include/generated/compile.h
CHK kernel/config_data.h
make[3]: `arch/x86/realmode/rm/realmode.bin' is up to date.
