Subject: [PATCH 10/13] drm/radeon: return -ENOENT in fence_wait_next v2
Date: Wed, 2 May 2012 00:00:55 -0400 [thread overview]
Message-ID: <1335931258-11756-11-git-send-email-j.glisse@gmail.com> (raw)
In-Reply-To: <1335931258-11756-1-git-send-email-j.glisse@gmail.com>
From: Christian König <deathsimple@vodafone.de>
We should signal the caller that we haven't waited at all.
v2: only change fence_wait_next not fence_wait_last.
