[PATCH] drm/i915: blacklist lid status: Sony VGN-BX196VP, Dell Inspiron 700m

[Surbhi Palande]

BugLink: https://bugs.launchpad.net/bugs/515246

Sony VGN-BX196VP and Dell Inspiron 700m report lid status as closed
when it is open. This leads to a "no connectors reported" error at startup.
Blacklisting them, to always return a connected status for the default
lvds connector.

Due to lack of hardware, I have not tested this patch on my own. Further
testing shall be helpful.

As far as I know, this should already be covered by:

drm/i915: give up on 8xx lid status

[Surbhi Palande]

Hi Eric,

Yes I agree. Thanks for the comment.

However, the "drm/i915: give up on 8xx lid status" will work for the
Dell Inspiron 700m. But, the Sony VGN-BX196VP will still need to be
blacklisted as it is a 915GM device.

If you agree with this, I will rewrite the patch and send you another
version.

Thanks!

Warm Regards,
Surbhi.
