PCI: cadence: Check for the existence of cdns_pcie::ops before using it

Browse source

[ Upstream commit 49a6c160ad ]

cdns_pcie::ops might not be populated by all the Cadence glue drivers. This
is going to be true for the upcoming Sophgo platform which doesn't set the
ops.

Hence, add a check to prevent NULL pointer dereference.
