From 90bd1f46caa9ad0d51ec48c91f3c3a616d6d6b8c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 19 Nov 2014 11:18:47 +0100 Subject: [PATCH] drm/i915: Tune down sink crc timeout dmesg output For whatever reasons this can happen. For real testcases the test will notice the -EIO and fall over, but we also have some testcases that just read all debugfs files. And that shouldn't cause dmesg spam. So tune it down a bit so that we still have the information for debugging. And change the errno so that real testcases can easily differentiate.
