The interrupt handling code was getting the struct device* from a struct snd_soc_component* stored in struct cs42l42_private. If the interrupt was asserted before ASoC calls component_probe() the snd_soc_component* will be NULL.
The stored snd_soc_component* is not actually used for anything other than indirectly getting the struct device*. Remove it, and store the struct device* in struct cs42l42_private.
