Subject: [PATCH 5.8 51/85] phy: ti: am654: Fix a leak in serdes_am654_probe()

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit 850280156f6421a404f2351bee07a0e7bedfd4c6 ]

If devm_phy_create() fails then we need to call of_clk_del_provider(node)
to undo the call to of_clk_add_provider().
