If the mach driver's probe is called ahead of codec driver's probe, the kernel will print -517 error message although the audio still works finally: acp_pdm_mach acp_pdm_mach.0: snd_soc_register_card(acp) failed: -517 we could workaround this issue by moving the registration of mach platform_dev to plat driver's probe.
