Subject: [PATCH 2/3] iio: adc: stm32-adc: improve calibration error log
Date: Tue, 15 Nov 2022 11:31:22 +0100 [thread overview]
Message-ID: <20221115103124.70074-3-olivier.moysan@foss.st.com> (raw)
In-Reply-To: <20221115103124.70074-1-olivier.moysan@foss.st.com>
Add more information in calibration error log to differentiate
single-ended and differential calibration.
