Subject: [PATCH 5.17 086/225] phy: ti: Add missing pm_runtime_disable() in serdes_am654_probe

From: Miaoqian Lin <linmq006@...il.com>

[ Upstream commit ce88613e5bd579478653a028291098143f2a5bdf ]

The pm_runtime_enable() will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
Add missing pm_runtime_disable() for serdes_am654_probe().
