[PATCH 4.9 061/164] of: fix sparse warning in of_pci_range_parser_one

From: Greg Kroah-Hartman
Date: Tue May 23 2017 - 16:29:45 EST


4.9-stable review patch. If anyone has any objections, please let me know.

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

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.
