From 890f3359f7b84d7015104360d647ccac5f515542 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 14 Sep 2010 16:46:59 +0100 Subject: [PATCH] drm/i915/i2c: Track the parent encoder rather than just the dev The SDVO proxy i2c adapter wants to be able to use information stored in the encoder, so pass that through intel_i2c rather than iterate over all known encoders every time.
