Package: initscripts
Version: 3.14-4devuan1
Severity: important
Tags: patch

Since upgrading i noticed the backlight behaviour for amd graphics changed, it
used to be the driver default to turn on at max brightness but on my system it
starts at 32 out of 255 as it seems that's now the driver default value.

I'm attaching patches for both initscripts 3.14 and 3.15 to address the change
in code style on the later, this carries the intention that the patch can be
added to an update of 3.14 before the Trixie point release without stepping on
the shipping schedule for 3.15.

Have a great day.
