SoC: rt274: Fix internal jack assignment in set_jack callback
[ Upstream commit 04268bf2757a125616b6c2140e6250f43b7b737a ] When we call snd_soc_component_set_jack(component, NULL, NULL) we should set rt274->jack to passed jack, so when interrupt is triggered it calls snd_soc_jack_report(rt274->jack, ...) with proper value. This fixes problem in machine where in register, we call snd_soc_register(component, &headset, NULL), which just calls rt274_mic_detect via callback. Now when machine driver is removed "headset" will be gone, so we need to tell codec driver that it's gone with: snd_soc_register(component, NULL, NULL), but we also need to be able to handle NULL jack argument here gracefully. If we don't set it to NULL, next time the rt274_irq runs it will call snd_soc_jack_report with first argument being invalid pointer and there will be Oops.
