Subject: dm: core: Tweak device_is_on_pci_bus() for code size
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=61fc132051740e0378a5e71f3db6cb1581e970fe;p=u-boot.git

dm: core: Tweak device_is_on_pci_bus() for code size

This function cannot return true if PCI is not enabled, since no PCI
devices will have been bound. Add a check for this to reduce code size
where it is used.
