Subject: [PATCH 1/1] smiapp: Make VANA regulator optional
Date: Mon, 13 Feb 2017 17:39:29 +0200	[thread overview]
Message-ID: <1487000369-2188-1-git-send-email-sakari.ailus@linux.intel.com> (raw)

On ACPI based systems ACPI will control the camera module's power
resources. In that case the sensor driver does not explicitly need to
control them, thus make them optional.
