    Subject[PATCH 3.16 116/134] of: fix sparse warning in of_pci_range_parser_one
    3.16.47-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Rob Herring <robh@kernel.org>

    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.
