Subject: [PATCH] thermal: qcom-spmi-adc-tm5: suppress probe-deferral error message
Date:   Wed,  2 Nov 2022 16:26:30 +0100
Message-Id: <20221102152630.696-1-johan+linaro@kernel.org>

Precedence: bulk

Drivers should not be logging errors on probe deferral. Switch to using
dev_err_probe() to log failures when parsing the devicetree to avoid
errors like:

	qcom-spmi-adc-tm5 c440000.spmi:pmic@0:adc-tm@3400: get dt data failed: -517

when a channel is not yet available.
