Subject: [PATCH 07/13] ARM: dts: exynos: Override thermal by label in Exynos5250
Date: Tue,  1 Sep 2020 09:54:11 +0200	[thread overview]
Message-ID: <20200901075417.22481-8-krzk@kernel.org> (raw)
In-Reply-To: <20200901075417.22481-1-krzk@kernel.org>

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).
