	It is not mandatory that platform data is passed along the ac97 codec. Actually there are configuration without a battery connected to the ADC of the codec. This is for example the case for the PXA zylonite platform, so fix the NULL dereferencing by adding a test.

2017-09-19	mfd: wm97xx-core: core support for wm97xx Codec	Robert Jarzmik	1	-0/+366
	The WM9705, WM9712 and WM9713 are highly integrated codecs, with an audio codec, DAC and ADC, GPIO unit and a touchscreen interface. Historically the support was spread across drivers/input/touchscreen and sound/soc/codecs. The sharing was done through ac97 bus sharing. This model will not withstand the new AC97 bus model, where codecs are discovered on runtime.
