Subject: [RFC 10/19] HSI: omap_ssi_core: use pm_runtime_put instead of pm_runtime_put_sync
Date: Sat, 18 Jun 2016 18:27:00 +0200 [thread overview]
Message-ID: <1466267229-25012-11-git-send-email-sre@kernel.org> (raw)
In-Reply-To: <1466267229-25012-1-git-send-email-sre@kernel.org>
There is no need to disable the device synchronously, so
don't do it.
