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
