[PATCH] ALSA: Fix prototype for snd_soc_dai_link.init() function pointer

[Timur Tabi <timur@freescale.com>]

Change the snd_soc_dai_link.init() function to take a pointer to the
corresponding snd_soc_dai_link structure, instead of a pointer to a
snd_soc_codec structure.  This allows the initialization function to initialize
its own structure.

This is a fix for ALSA bug 3135
(https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3135).  Since I
don't have an ARM cross-compiler, and currently all ASoC drivers are for ARM
platforms only, I'm not sure if this fix is correct.
