+Subject: pwm: fix bad scaling due to use of integer type
+References: boo#1255928
+Patch-mainline: No, pending PR https://github.com/hramrach/lm-sensors/pull/12
+
+This fixes commit c1a1f4ff206c0e6959c3e4d6b19ba27963076d5e ("pwm: Move
+scaling factor from sensors prog to library") which didn't account for
+return type of `get_type_scaling()` being `int` rather than `double` or
+`float`, so the scaling was done by a factor of 2 instead of 2.55, thus
+making the result off by quite a lot.
