From a1b828f202ae45b4fce4d21e83679605feb87862 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 16 Jun 2023 11:09:24 +0200 Subject: [PATCH] soundwire: intel_ace2x: fix SND_SOC_SOF_HDA_MLINK dependency The ace2x driver can be build with or without mlink support, but when SND_SOC_SOF_HDA_MLINK is set to =m and soundwire is built-in, it fails with a link error: ld.lld: error: undefined symbol: hdac_bus_eml_sdw_wait_syncpu_unlocked >>> referenced by intel_ace2x.c >>> drivers/soundwire/intel_ace2x.o:(intel_link_power_up) in archive vmlinux.a ld.lld: error: undefined symbol: hdac_bus_eml_sdw_sync_arm_unlocked >>> referenced by intel_ace2x.c >>> drivers/soundwire/intel_ace2x.o:(intel_sync_arm) in archive vmlinux.a Add a Kconfig dependency that prevents that broken configuration but still allows soundwire to be a loadable module instead.
