From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit fbeeb822f6f45cadf154d7b7cff1c13537cd799d upstream.
f41f064cf4 ("PCI: Workaround missing pci_set_master in pci drivers") made
pci_enable_bridge() turn on bus mastering if the driver hadn't done so
already. It also added a warning in this case. But there's no reason to
warn about it unless it's actually a problem to enable bus mastering here.
This patch drops the warning because I'm not aware of any such problem.
