Subject: [PATCH v9 19/26] powerpc/pci: Rename pcibios_find_pci_bus()
Date: Tue,  3 May 2016 15:41:38 +1000	[thread overview]
Message-ID: <1462254105-24128-20-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1462254105-24128-1-git-send-email-gwshan@linux.vnet.ibm.com>

This renames pcibios_find_pci_bus() to pci_find_bus_by_node() to
avoid conflicts with those PCI subsystem weak function names, which
have prefix "pcibios". No logical changes introduced.
