Subject: of: base: make of_device_compatible_match() accept const device node
X-Git-Tag: v6.1-rc5~228^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=88269151be679b9accb2f1e73487eaeb9eae9e39;p=platform%2Fkernel%2Flinux-starfive.git

of: base: make of_device_compatible_match() accept const device node

of_device_is_compatible() accepts const device node pointer, there is
no reason why of_device_compatible_match() can't do the same.
