If anyone has any objections, please let me know. ------------------ From: Rob Herring commit eb3100365791b06242b8bb5c3c2854ba41dabfbc upstream. sparse gives the following warning for 'pci_space': ../drivers/of/address.c:266:26: warning: incorrect type in assignment (different base types) ../drivers/of/address.c:266:26: expected unsigned int [unsigned] [usertype] pci_space ../drivers/of/address.c:266:26: got restricted __be32 const [usertype] It appears that pci_space is only ever accessed on powerpc, so the endian swap is often not needed.
