[PATCH 5.4 053/138] net: ag71xx: add missed clk_disable_unprepare in error path of probe

[Greg Kroah-Hartman]

From: Huang Guobin <huangguobin4@xxxxxxxxxx>

[ Upstream commit befc113c56a76ae7be3986034a0e476d3385e265 ]

The ag71xx_mdio_probe() forgets to call clk_disable_unprepare() when
of_reset_control_get_exclusive() failed. Add the missed call to fix it.

Fixes: d51b6ce441d3 ("net: ethernet: add ag71xx driver")
