Yeah, > > > + &tegra_of_thermal_ops); CHECK: Alignment should match open parenthesis #423: FILE: drivers/thermal/tegra_soctherm.c:423: + tz = devm_thermal_zone_of_sensor_register(&pdev->dev, i, zone, + &tegra_of_thermal_ops); and if you align it, then, you get the warning: WARNING: line over 80 characters #423: FILE: drivers/thermal/tegra_soctherm.c:423: + &tegra_of_thermal_ops); And I did not want to add either of the above to the driver. But if you prefer tz over z, we can keep the first (check) then. What do you prefer?
