-Subject: [PATCH 1/8] backports: add led_trigger_blink{_oneshot}()
-
-When led support is deactivated in the kernel and
-CPTCFG_BACKPORT_BUILD_LEDS is set mac80211 references
-led_trigger_blink_oneshot() but it is not declared anywhere.
-
-This fixes the following build error:
-net/mac80211/led.c: In function 'ieee80211_led_rx':
-net/mac80211/led.c:25:2: error: implicit declaration of function 'led_trigger_blink_oneshot' [-Werror=implicit-function-declaration]
