SubjectRe: [PATCH] PCI: cadence: add missing return for plat probe

In subject and commit log:

PCI: cadence: Add missing return in cdns_plat_pcie_probe()

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

We should have a Fixes: tag here to show where this bug was
introduced. Look at previous git history to see the format. Maybe
also a stable tag so this will get backported to stable kernels.

Interesting that nobody noticed such an obvious bug until now.

Since the patch was sent by Li, that signoff should be last, per
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=v5.14#n365
