From a2634a5ffcafc31c343c6153ae487eb184c433a6 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 3 Jan 2024 16:52:04 +0100 Subject: [PATCH] r8169: fix building with CONFIG_LEDS_CLASS=m When r8169 is built-in but LED support is a loadable module, the new code to drive the LED causes a link failure: ld: drivers/net/ethernet/realtek/r8169_leds.o: in function `rtl8168_init_leds': r8169_leds.c:(.text+0x36c): undefined reference to `devm_led_classdev_register_ext' LED support is an optional feature, so fix this issue by adding a Kconfig symbol R8169_LEDS that is guaranteed to be false if r8169 is built-in and LED core support is a module. As a positive side effect of this change r8169_leds.o no longer is built under this configuration.
