[PATCH 4.19.y-cip 11/22] thermal: rcar_gen3_thermal: Register hwmon sysfs interface


Biju Das <biju.das@...>
 

From: Marek Vasut <marek.vasut+renesas@...>

commit 6269e9f790e8d442b3e1529bf3b3de452dd4ac92 upstream.

Register the hwmon sysfs interface on R-Car Gen3 thermal driver to
align it with Gen2 driver. Use devm_add_action() to unregister the
hwmon interface automatically.
