Subject: powerpc/powernv: Use __raw_[rm_]writeq_be() in pci-ioda.c
X-Git-Tag: v4.19~866^2~164
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=001ff2ee137de5fb7a099a36f7b29488114964fb;p=platform%2Fkernel%2Flinux-rpi.git

powerpc/powernv: Use __raw_[rm_]writeq_be() in pci-ioda.c

This allows us to squash some sparse warnings and also avoids having
to do explicity endian conversions in the code.
