Subject: [PATCH v10 2/8] drivers: thermal: tsens: Don't hardcode sensor slope
Date: Wed, 17 Feb 2021 20:40:04 +0100 [thread overview]
Message-ID: <20210217194011.22649-3-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20210217194011.22649-1-ansuelsmth@gmail.com>
Function compute_intercept_slope hardcode the sensor slope to
SLOPE_DEFAULT. Change this and use the default value only if a slope is
not defined. This is needed for tsens VER_0 that has a hardcoded slope
table.
