From 59cdb63d529c81fc8ac0620ad50f29d5fb4411c9 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 4 Jul 2013 23:35:28 +0200 Subject: drm/i915: kill dev_priv->rps.lock Now that the rps interrupt locking isn't clearly separated (at elast conceptually) from all the other interrupt locking having a different lock stopped making sense: It protects much more than just the rps workqueue it started out with. But with the addition of VECS the separation started to blurr and resulted in some more complex locking for the ring interrupt refcount. With this we can (again) unifiy the ringbuffer irq refcounts without causing a massive confusion, but that's for the next patch. v2: Explain better why the rps.lock once made sense and why no longer, requested by Ben.
