[PATCH 1/2] ASoC: Intel: bxt_da7219_max98357a: Fix kernel ops due to COMP_DUMMY change

[Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>]

The change to avoid dummy components will leave the component name and
dai_name NULL which will cause NULL dereference when trying to access to
it in the machine driver when applying fixups.

Fixes: 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()")
