[Pkg-acpi-devel] Bug#524838: Patch panabright.sh to work with the new panasonic_laptop driver

[Matthias Hentges]

Package: acpi-support
Version: 0.109-11
Severity: important
Tags: patch

The Debian version of panabright.sh only works with the old "pcc_acpi"
driver, which doesn`t compile against
any recent kernel. The out-of-kernel pcc_acpi driver has since been
replaced by the in-kernel panasonic-laptop module.

If affected by the bug, one can not use the brightness hotkeys to
adjust the brightness of the LCD, as the new driver uses
/sys/* while the old one used /proc/*.

The attached patch detects which driver is active and acts
accordingly, fixing the non-functional brightness hotkeys.
Please note that I was not able to test the script with the old pcc_acpi driver.
