Subject: net: mvmdio: disable/unprepare clocks in EPROBE_DEFER case
From: Tobias Jordan <Tobias.Jordan@xxxxxxxxxxxxxx>
[ Upstream commit 589bf32f09852041fbd3b7ce1a9e703f95c230ba ]
add appropriate calls to clk_disable_unprepare() by jumping to out_mdio
in case orion_mdio_probe() returns -EPROBE_DEFER.
Found by Linux Driver Verification project (linuxtesting.org).
