   4 Subject: [PATCH 4/4] hwmon: (tps23861) correct shunt LSB values
   5
   6 Current shunt LSB values got reversed during in the
   7 original driver commit.
   8
   9 So, correct the current shunt LSB values according to
  10 the datasheet.
  11
  12 This caused reading slightly skewed current values.
