Yeah,

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?
