Also no need to repeat 'sc7180', it is already clear from the prefix.

common way to do this kind of unwinding in the kernel would be to add

pwm_backlight_probe() re-assigns pb->levels for every brightness
level. This is not needed and was likely not intended, since
neither side of the assignment changes during the loop. Assign
the field only once.
