Subject: [PATCH 3/7] drm/i915: Don't return error on sink crc stop.
Date: Thu, 23 Jul 2015 16:35:46 -0700	[thread overview]
Message-ID: <1437694550-5667-2-git-send-email-rodrigo.vivi@intel.com> (raw)
In-Reply-To: <1437694550-5667-1-git-send-email-rodrigo.vivi@intel.com>

If we got to the point where we are trying to stop sink CRC
the main output of this function was already gotten properly,
so don't return the error and let userspace use the crc data.

Let's replace the errnos returns with some log messages.
