[PATCH RESEND] ACPI: Blacklist Win8 OSI for some HP laptop 2013 models

From: Takashi Iwai
Date: Mon Jan 13 2014 - 06:14:26 EST


The BIOS on recent HP laptops behaves differently with Win8 OSI,
e.g. no backlight control and no rfkill are available. List them in
the blacklist as a workaround.

This patch tries to reduce the added items by matching "G1" suffix,
e.g. machines are named like "HP ProBook 430 G1".

Rafael, could you check this?
If the problem were only about the backlight, we could fix differenly,
but BIOS on these machines seems to switching more other functions
like rfkill.

thanks,

Takashi
