From 098bd8911a5eacc3b70fdc09fa4084657511c584 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 18 Feb 2016 08:17:52 +0000 Subject: [PATCH] ASoC: rsnd: Parent SSI attach is not needed if not clock master Parent SSI is needed if it is PIN sharing and clock master, otherwise, not needed. But, whether clockk master is judged on .set_fmt, thus, it can't call rsnd_ssi_parent_attach() on .probe. Now, .pcm_new will be called after .set_fmt, so this patch reuses it at this point.
