| Subject: hwmon: (emc1403) Support full range of known chip revision numbers |
| |
| From: Josef Gajdusek <atx@atx.name> |
| |
| commit 3a18e1398fc2dc9c32bbdc50664da3a77959a8d1 upstream. |
| |
| The datasheet for EMC1413/EMC1414, which is fully compatible to |
| EMC1403/1404 and uses the same chip identification, references revision |
| numbers 0x01, 0x03, and 0x04. Accept the full range of revision numbers |
| from 0x01 to 0x04 to make sure none are missed. |
