Subject: [PATCH 02/24] rtc: pm8xxx: drop spmi error messages
Date:   Thu, 26 Jan 2023 15:20:35 +0100
Message-Id: <20230126142057.25715-3-johan+linaro@kernel.org>
In-Reply-To: <20230126142057.25715-1-johan+linaro@kernel.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Drop the unnecessary error messages after every spmi regmap access,
which are not expected to fail.
