3.13.11.6 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Axel Lin <axel.lin@xxxxxxxxxx> commit c024044d4da2c9c3b32933b4235df1e409293b84 upstream. The module test script for the adm1021 driver exposes a cache problem when writing temperature limits. temp_min and temp_max are expected to be stored in milli-degrees C but are stored in degrees C.
