The max98357a driver depends on GPIOLIB. This may cause the following build failure.
sound/soc/codecs/max98357a.c: In function 'max98357a_daiops_trigger': sound/soc/codecs/max98357a.c:30:3: error: implicit declaration of function 'gpiod_set_value' sound/soc/codecs/max98357a.c: In function 'max98357a_codec_probe': sound/soc/codecs/max98357a.c:55:2: error: implicit declaration of function 'devm_gpiod_get' sound/soc/codecs/max98357a.c:61:2: error: implicit declaration of function 'gpiod_direction_output'
Seen with mips:allmodconfig as well as various randconfig builds.
