From: Robert Coulson <rob.coulson@xxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 39c627a084475e8a690a4a9e7601410ca173ddd2 upstream.
After the conversion rate is changed, the zbits are not updated,
but should be, since they are used later in the set_temp function.
Fixes: a50d9a4d9ad3 ("hwmon: (ds1621) Fix temperature rounding operations")
