Commit 2b9c8d2b3c89 ("ASoC: rt5640: Add the HDA header support") adds re-queuing of the jack_work on resume when rt5640->jd_src != 0.
But the jack_work will unconditionally deref rt5640->jack and that might be NULL. E.g. the sound/soc/intel/boards/bytcr_rt5640.c machine driver call snd_soc_component_set_jack(codec, NULL, NULL) from pre_suspend to disable the IRQ to avoid spurious wakeups, so when rt5640_resume() runs rt5640->jack will be NULL in this case.
Make the queueing of the work conditional on rt5640->jack instead of on rt5640->jd_src to fix this.
