Comment 1 Kai Uwe Broulik 2014-12-13 20:11:20 UTC 
Git commit 34c13c3acb558753110a44668d1ff9239ce128eb by Kai Uwe Broulik.
Committed on 13/12/2014 at 20:06.
Pushed by broulik into branch 'master'.

Revert "Emit signal when maximum brightness changes"

Better revert this until I can dig deeper into potential race conditions
since this patch is probably the wrong approach in the first place.

This reverts commit 697e505f37b9128d68ef2b0ce5c9d7f80ca422ff.
