Subject: [PATCH 09/18] regulator: add device reference to regulator_dev
Date: Mon, 28 Sep 2020 17:50:32 +0200	[thread overview]
Message-ID: <20200928155041.32649-10-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200928155041.32649-1-m.felsch@pengutronix.de>

It is useful to know the physical device a regulator_dev belongs to.
This is at least needed for the new deep-probe mechanism. It is also
useful for a few regulator drivers to drop their own device_d reference.
