From c3a3d3c41b74b05267bab6173f2a8224a1443ba6 Mon Sep 17 00:00:00 2001 From: Christophe Jaillet Date: Thu, 15 Jun 2017 07:53:11 +0200 Subject: ASoC: rockchip: Fix an error handling in 'rockchip_i2s_probe' If this memory allocation fail, we must disable what has been enabled. Do not return immediately but go thrue the error handling path instead. Also use 'devm_kmemdup' instead of 'devm_kzalloc+memcpy' to simplify code.
