But these will be replaced to more generic "component" soon, and will need more generic method to get each connected component pointer from rtd. This patch adds new snd_soc_rtdcom_xxx() to connect/disconnect component to rtd. It means same as previous "platform" / "codec" pointer style, but more generic. We can find necessary component pointer from rtd by using component driver name on snd_soc_rtdcom_lookup(). Here, the reason why it uses "driver name" is that "component name" was created by fmt_single_name() and difficult to use it from driver. Driver of course knows its "driver name", thus, using it is more easy.
