ath9k: fix build error with LEDS_CLASS=m
When CONFIG_ATH9K is built-in but LED support is in a loadable module, both ath9k drivers fails to link: x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_deinit_leds': gpio.c:(.text+0x36): undefined reference to `led_classdev_unregister' x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_init_leds': gpio.c:(.text+0x179): undefined reference to `led_classdev_register_ext' The problem is that the 'imply' keyword does not enforce any dependency but is only a weak hint to Kconfig to enable another symbol from a defconfig file. Change imply to a 'depends on LEDS_CLASS' that prevents the incorrect configuration but still allows building the driver without LED support. The 'select MAC80211_LEDS' is now ensures that the LED support is actually used if it is present, and the added Kconfig dependency on MAC80211_LEDS ensures that it cannot be enabled manually when it has no effect.
