soc_dpcm_runtime_update() operates on a ASoC card as a whole. Currently it takes a snd_soc_dapm_widget as its only parameter though. The widget is then used to look up the card and is otherwise unused. This patch changes the function to take a pointer to the card directly. This makes it possible to to call soc_dpcm_runtime_update() for updates which are not related to one specific widget.
