[PATCH] hwmon: (ds1621) Update zbits after conversion rate change

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Robert Coulson <rob.coulson@xxxxxxxxx>

After the conversion rate is changed, the zbits are not updated,
but should be, since they are used later in the set_temp function.

This issue was noticed and reported by Murat Ilsever.
