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

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.

This if statement needs to be
		if (config & (ADM1278_VOUT_EN | ADM1278_TEMP1_EN) != ADM1278_VOUT_EN | ADM1278_TEMP1_EN)

          Hi Guenter,

             The below warning shown by checkpatch after changes,

                  WARNING: line over 80 characters
                   #38: FILE: drivers/hwmon/pmbus/adm1275.c:672:
                   + if (config & (ADM1278_VOUT_EN | ADM1278_TEMP1_EN) != ADM1278_VOUT_EN | ADM1278_TEMP1_EN) {
 
                   total: 0 errors, 1 warnings, 24 lines checked

              I didn't see any if() condition made as two line in the driver . Is this acceptable warning ?

         Thanks
         Mani.E

The warning is (or should be) gone in the latest upstream kernel -
the line length limit is now 100 bytes. Just ignore that warning,
or rebase your patch to the latest upstream kernel.
