[PATCH 5.5 021/367] net: phy: at803x: disable vddio regulator

[Greg Kroah-Hartman]

From: Michael Walle <michael@xxxxxxxx>

[ Upstream commit 2318ca8aef3877da2b16b92edce47a497370a86e ]

The probe() might enable a VDDIO regulator, which needs to be disabled
again before calling regulator_put(). Add a remove() function.

Fixes: 2f664823a470 ("net: phy: at803x: add device tree binding")
