Sorry, I didn't know the old version was still there.
For some reason until I removed the staging samsung-laptop from the
Makefile, the new one didn't get installed.

Done. So far tested on n230 only.

It fails to insert without "force" with the same message. With force it
installs, but doesn't seem to work, at least for brightness buttons.

Please find modinfo output and dmesg output attached.

Thank you :)

Sincerely,
Nick
