Subject: [PATCH 5.15 777/917] PCI: j721e: Fix j721e_pcie_probe() error path

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 496bb18483cc0474913e81e18a6b313aaea4c120 ]

If an error occurs after a successful cdns_pcie_init_phy() call, it must be
undone by a cdns_pcie_disable_phy() call, as already done above and below.

Update the goto to branch at the correct place of the error handling path.
