[PATCH] drm/i915: Add Sony VGN-BZ12VN to ACPI LID quirk list

[PATCH] drm/i915: Add Sony VGN-BZ12VN to ACPI LID quirk list

[Hubert Hesse]

Hi there,

I'm referring to my Bugreport 15473.

I wanted to use KMS with the latest kernel on my Sony VGN-BZ12VN.
Similiar to Bug 14649 and 14554 `cat /proc/acpi/button/lid/LID0/state`
always reports "state: closed" to me. 
A blank screen is the result for me, when booting with KMS enabled.

I figured out to add my Laptop to the ACPI LID quirk list.
Sorry for the double post. Its the first time I hand in a patch. 

So here it comes:


The Sony Vaio VGN-BZ12VN laptop always reports the LID
status as closed, therefore add it into the acpi lid quirk list.

In place of more quirk patches, I've pushed the patch removing the use
of ACPI LID status for LVDS detection.
