[PATCH v4 09/10] hwmon: (tmp421) ignore non-channel related DT nodes

From: Krzysztof Adamski <hidden>
Date: 2021-10-12 09:30:36
Also in: linux-hwmon
Subsystem: hardware monitoring, the rest · Maintainers: Guenter Roeck, Linus Torvalds

In case the DT contains some nodes not describing the input channels,
ignore them instead of exiting with error.
