From c2b9152f098e213dc5f2e8a4dbbfe090302c58ed Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 14 Feb 2012 22:37:19 +0100 Subject: [PATCH] drm/i915: add dev_priv to intel_gmbus This way we can free up the bus->adaptor.algo_data pointer and make it available for use with the bitbanging fallback algo.
