[PATCH] platform/x86: thinkpad_acpi: Fix a max_brightness of thinklight

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Thinklight has only two values, on/off so it's reasonable for max_brightness to be 0 and 1 as if you write anything between 0 and 255 it will be 255 anyway so there's no point for it to be 255.

Also sorry for repeated messages, I got no reply so I'm trying to figure out what I did wrong.
