Subject: [PATCH v4] hwmon:(adm1275) Enable adm1278 ADM1278_TEMP1_EN

The adm1278 temp attribute need it for openbmc platform .
This feature not enabled by default, so PMON_CONFIG needs to enable it.

v4:
---
Reported-by: kernel test robot <[email protected]>
v3:
----
fix invalid signed-off.
removed checkpath warnings.
write ADM1278_TEMP1_EN and ADM1278_VOUT_EN conf in single line operation.
v2:

add Signed-off-by.
removed ADM1278_TEMP1_EN check.

In addition to the other comment - please never send a new version of a patch
with the same sequence number. There are now two different versions of this patch,
both tagged "v4".
