Subject: [PATCH v9 3/7] iio: accel: kionix-kx022a: Warn on failed matches and assume compatibility
Date: Sat, 16 Sep 2023 14:38:49 +0200	[thread overview]
Message-ID: <b587cfec2f3350623277005f62121864bee857c7.1694867379.git.mehdi.djait.k@gmail.com> (raw)
In-Reply-To: <cover.1694867379.git.mehdi.djait.k@gmail.com>

Avoid error returns on a failure to match and instead just warn with
assumption that we have a correct dt-binding telling us that
some new device with a different ID is backwards compatible.
