Building with 'make W=1' shows some warnings about empty function-style macros:
sound/core/pcm_memory.c: In function 'preallocate_pages': sound/core/pcm_memory.c:236:49: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 236 | preallocate_info_init(substream);
sound/core/seq_device.c: In function 'snd_seq_device_dev_register': sound/core/seq_device.c:163:41: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 163 | queue_autoload_drivers();
Change them to empty inline functions, which are more robust here.
