[PATCH 5.13 177/300] ASoC: rt5682: Implement remove callback

[Greg Kroah-Hartman]

From: Stephen Boyd <swboyd@xxxxxxxxxxxx>

[ Upstream commit 87b42abae99d3d851aec64cd4d0f7def8113950e ]

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.
