[PATCH v10 2/8] drivers: thermal: tsens: Don't hardcode sensor slope

From: Ansuel Smith
Date: Wed Feb 17 2021 - 19:57:26 EST


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.
