From: Arnd Bergmann <arnd@xxxxxxxx> The new PM functions require code that is part of the snd-acp-legacy-common module: x86_64-linux-ld: sound/soc/amd/acp/acp-pci.o: in function `snd_acp_resume': acp-pci.c:(.text+0x23): undefined reference to `acp_init' x86_64-linux-ld: acp-pci.c:(.text+0x58): undefined reference to `acp_enable_interrupts' x86_64-linux-ld: sound/soc/amd/acp/acp-pci.o: in function `snd_acp_suspend': acp-pci.c:(.text+0x89): undefined reference to `acp_deinit' x86_64-linux-ld: sound/soc/amd/acp/acp-pci.o: in function `acp_pci_remove': acp-pci.c:(.text+0xec): undefined reference to `acp_deinit' x86_64-linux-ld: sound/soc/amd/acp/acp-pci.o: in function `acp_pci_probe': acp-pci.c:(.text+0x26b): undefined reference to `acp_init' Select that Kconfig symbol as is done for the other frontends.
