From 17508c32dd65649d2617c1c52b32b02bdb54b793 Mon Sep 17 00:00:00 2001
From: Ryder Lee <ryder.lee@mediatek.com>
Date: Tue, 2 Jan 2018 19:47:18 +0800
Subject: [PATCH 180/224] ASoC: mediatek: fix error handling in
mt2701_afe_pcm_dev_probe()
Fix unbalanced error handling path which will get incorrect counts
if probe failed. The .remove() should be adjusted accordingly.
