From: Ansuel Smith Date: Tue, 20 Apr 2021 18:33:35 +0000 (+0200) Subject: thermal/drivers/tsens: Don't hardcode sensor slope X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d51769b2e75bb33c56c8f9ee933eca2d92b375b;p=linux.git thermal/drivers/tsens: Don't hardcode sensor slope 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.
