From 16e9a21f33cda9d48b70ff54e1ed2e4a77497bc6 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Thu, 6 Nov 2014 09:26:38 +0200 Subject: [PATCH] drm/i915: Make __wait_seqno non-static and rename to __i915_wait_seqno So that it can be used by the flip code to wait for rendering without holding any locks.
