Subject: hwmon: (ibmpowernv) add a get_sensor_type() routine
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c4ad47206425e8f38928413ab35f59bd294ddbc2;p=deliverable%2Flinux.git

hwmon: (ibmpowernv) add a get_sensor_type() routine

It will help in adding different compatible properties, coming from a
new device tree layout for example.
