Subject: [RFC/PATCH 2/2] ASoC: rt5682: Implement remove callback
Date: Sat,  8 May 2021 00:51:51 -0700	[thread overview]
Message-ID: <20210508075151.1626903-2-swboyd@chromium.org> (raw)
In-Reply-To: <20210508075151.1626903-1-swboyd@chromium.org>

Let's implement a remove callback for this driver that's similar to the
shutdown hook, but also disables the regulators before they're put by
devm code.
