Subject: [PATCH 18/33] ARM: dts: exynos: Override thermal by label in Trats
Date:   Sun, 30 Aug 2020 15:51:45 +0200
Message-Id: <20200830135200.24304-18-krzk@kernel.org>
In-Reply-To: <20200830135200.24304-1-krzk@kernel.org>
References: <20200830135200.24304-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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).
