Subject: of: fix sparse warning in of_pci_range_parser_one
From: Rob Herring <robh@xxxxxxxxxx>
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] <noident>
It appears that pci_space is only ever accessed on powerpc, so the endian
swap is often not needed.
