From 5f86d6c78b4662782e405344da71782d355c1063 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Sat, 19 Oct 2013 17:31:55 +0200 Subject: ASoC: omap: rx51: Use devm_snd_soc_register_card MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch converts the rx51 ASoC module to use devm_snd_soc_register_card. It also adds module alias to support driver autoloading.
