From 17c40f3c94bc2279b879ea9ceb3eea973bcd1ac4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 7 Aug 2024 09:55:53 +0200 Subject: [PATCH] leds: blinkm: Fix CONFIG_LEDS_CLASS_MULTICOLOR dependency With CONFIG_LEDS_CLASS_MULTICOLOR=m, a builtin leds-blinkm driver causes a link failure: arm-linux-gnueabi-ld: drivers/leds/leds-blinkm.o: in function `blinkm_set_mc_brightness': leds-blinkm.c:(.text.blinkm_set_mc_brightness+0xc): undefined reference to `led_mc_calc_color_components' Add a more specific dependency that only allows multicoler mode to be enabled for blinkm if it can build and link.
