Subject: [PATCH] soc: samsung: chipid: Remove the regmap lookup error log
Date: Wed, 21 Aug 2019 17:05:39 +0200	[thread overview]
Message-ID: <20190821150539.31207-1-s.nawrocki@samsung.com> (raw)
In-Reply-To: CGME20190821150548eucas1p15139f733b00e3a1a107efe39f6712fe9@eucas1p1.samsung.com

In commit 40d8aff614f7 ("soc: samsung: chipid: Convert exynos-chipid
driver to use the regmap API") of_find_compatible_node() call was
substituted with syscon_regmap_lookup_by_compatible() but also an error
log was added for case where lookup fails. On multiplatform the lookup
will always fail on any non-samsung device so the log is incorrect.
Remove the error log and just return an error code from
syscon_regmap_lookup_by_compatible() which internally calls
of_find_compatible_node().
