From mboxrd@z Thu Jan 1 00:00:00 1970 From: koro.chen@mediatek.com (Koro Chen) Date: Tue, 23 Jun 2015 19:01:20 +0800 Subject: [PATCH] ASoC: mediatek: Fix unbalanced calls to runtime suspend/resume Message-ID: <1435057280-21316-1-git-send-email-koro.chen@mediatek.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This adds call to runtime suspend in dev remove. It fixs the problem that suspend is not called in the case of CONFIG_PM=n. It also fixs build warning when CONFIG_PM=n.
