Subject: [PATCH 5.15 141/917] PCI: cadence: Add cdns_plat_pcie_probe() missing return

From: Li Chen <lchen@...arella.com>

commit 27cd7e3c9bb1ae13bc16f08138edd6e4df3cd211 upstream.

When cdns_plat_pcie_probe() succeeds, return success instead of falling
into the error handling code.

Fixes: bd22885aa188 ("PCI: cadence: Refactor driver to use as a core library")
