ALSA: ac97: fix build regression
The ac97_bus_type structure is no longer declared in this file: sound/ac97/bus.c: In function 'ac97_codec_add': sound/ac97/bus.c:112:27: error: 'ac97_bus_type' undeclared (first use in this function); did you mean 'bus_type'? 112 | codec->dev.bus = &ac97_bus_type; | ^~~~~~~~~~~~~ | bus_type sound/ac97/bus.c:112:27: note: each undeclared identifier is reported only once for each function it appears in sound/ac97/bus.c: In function 'snd_ac97_codec_driver_register': sound/ac97/bus.c:191:28: error: 'ac97_bus_type' undeclared (first use in this function); did you mean 'ac97_bus_reset'? 191 | drv->driver.bus = &ac97_bus_type; Include the header that contains the declaration and make sure the definition is const but not static.
