Subject: [PATCH 09/15] net: ag71xx: add missed clk_disable_unprepare in error
path of probe
Patch-mainline: v5.8-rc7
Git-commit: befc113c56a76ae7be3986034a0e476d3385e265
References: git-fixes
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")
