There are two call sites for snd_soc_post_component_init(), one passes 0 and the other 1 for the 'dailess' parameter of snd_soc_post_component_init(). Depending on whether 'dailess' is 0 or 1 snd_soc_post_component_init() runs different code at the beginning and the end of the function. The patch moves this conditional code out of snd_soc_post_component_init() and into the call sites. This removes the need for snd_soc_post_component_init() to know whether it is called for a DAI link or a aux dev.
Also do the initialization of rtd->card when the rtd struct is allocated.
