Subject: Re: [PATCH v3] drm/i915: Honor SSC quirk table over the default, unless set by user
Date: Wed, 09 Nov 2011 17:30:29 +0100	[thread overview]
Message-ID: <4EBAAAA5.7030807@fedoraproject.org> (raw)
In-Reply-To: <1320855178.5081.9.camel@fauix11.informatik.uni-erlangen.de>

Additional note: while I've not touched the line since it does not
affect me, it seems that i915_panel_use_ssc *cannot* be less than 0
since that variable is declared as unsigned.

So the last line (the value in dev_priv) will never be used to determine
whether SSC is used anyway. Keith probably knows more since he
introduces that check in the commit that my patch referred to.
