   4 Subject: [PATCH 02/10] drivers: thermal: tsens: Don't hardcode sensor slope
   5
   6 Function compute_intercept_slope hardcode the sensor slope to
   7 SLOPE_DEFAULT. Change this and use the default value only if a slope is
   8 not defined. This is needed for tsens VER_0 that has a hardcoded slope
   9 table.
