I can reproduce this, but I question the hard dependency on GPIOLIB in
the amplifier Kconfig:

	max98357a->sdmode = devm_gpiod_get_optional(&pdev->dev,
				"sdmode", GPIOD_OUT_LOW);

If the gpio is optional, max98357a.c should build and compile without
GPIOLIB, no?

I can't reproduce this one with Mark's for-next branch, this was fixed I
believe.
