From 96154f2faba540281073243d61108d1705d19c6d Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 14 Dec 2011 13:57:00 +0100 Subject: [PATCH] drm/i915: switch ring->id to be a real id ... and add a helpr function for the places where we want a flag. This way we can use ring->id to index into arrays. v2: Resurrect the missing beautification-space Chris Wilson noted. I'm moving this space around because I'll reuse ring_str in the next patch.
