Subject: PCI: Log all resource claims
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=432b936fa6b7a8ad5d7ea55be9522c6dc24b9554;p=thirdparty%2Flinux.git

PCI: Log all resource claims

There are two ways to graft resource into resource tree in PCI,
pci_assign_resource() and pci_claim_resource(). Only the former logs
the action, which complicated troubleshooting the cases where resources
are assigned by pci_claim_resource(), which mostly assigns the addresses
inherited from the FW.

Add logging into pci_claim_resource() to make troubleshooting easier.
