Subject: [PATCH] ASoC: atmel-classd: sync regcache when resuming
Date: Mon, 15 May 2017 10:36:17 +0200 [thread overview]
Message-ID: <20170515083617.16742-1-quentin.schulz@free-electrons.com> (raw)
The PM functions used in this driver are the ones defined in
sounc/soc/soc-core.c.
When suspending (using snd_soc_suspend), the regcache is marked dirty
but is never synced on resume.
Sync regcache on resume of Atmel ClassD device.
