From 9900a4226c785dbb32c08af5ae8fbbf1fc4c31d0 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 25 Sep 2017 01:38:54 +0000 Subject: [PATCH] ASoC: remove unneeded dai->driver->ops check On soc_add_dai(), it uses null_dai_ops if driver doesn't have its own ops. This means, dai->driver->ops never been NULL. dai->driver->ops check is not needed. This patch removes it.
