From 6ed0f796c22cd638fac60f29ff72b3a7a03485e6 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sun, 8 Jul 2012 19:41:43 +0200 Subject: [PATCH] drm/i915: use staged outuput config in tv->mode_fixup The "is this encoder cloned" check will be reused by the lvds encoder, hence exract it. v2: Be a bit more careful about that we need to check the new, staged ouput configuration in the check_non_cloned helper ... v3: Kill the double negation with s/!non_cloned/is_cloned/, suggested by Jesse Barnes.
