checkpatch is really for patches. Using -f is a
convenience ability. You can limit what messages
checkpatch emits by using "--types=<FOO[,BAR...]>"

You can show what message classifications are being
used by adding "--show-types".

Well, here the general kernel style is to put
the logical && or || test at the end of the
previous line so:

if (devattr == &sensor_dev_attr_fan1_max_alarm.dev_attr ||
devattr == &sensor_dev_attr_fan1_min_alarm.dev_attr ||
devattr == &sensor_dev_attr_fan1_fault.dev_attr ||
devattr == &sensor_dev_attr_gpio1_alarm.dev_attr ||
devattr == &sensor_dev_attr_gpio2_alarm.dev_attr) {

would likely be preferred.

This may be indentation alignment but I don't follow
how this is a problem.

Is this change from Lindent or checkpatch?
