Subject: sh: Do not apply virt_to_phys() to a physical address
X-Git-Tag: upstream/snapshot3+hdmi~16124^2~62^2~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb3118f652ea7751ecf6a7e467bb637895e3be3b;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

sh: Do not apply virt_to_phys() to a physical address

The variable 'phys' already contains the physical address to flush. It
is not a virtual address and should not be passed to virt_to_phys().
