Subject: ARM: dts: exynos: Override thermal by label in Midas
X-Git-Tag: v5.15~2574^2~54^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e4cf0a4dba7f0bd579dc96f24d8e6134995005c5;p=platform%2Fkernel%2Flinux-starfive.git

ARM: dts: exynos: Override thermal by label in Midas

Using full paths to extend or override a device tree node is error prone
since if there was a typo error, a new node will be created instead of
extending the node as it was desired.  This will lead to run-time errors
that could be hard to detect.

A mistyped label on the other hand, will cause a dtc compile error
(during build time).
