Subject: [PATCH v2 2/6] drm/i915: Reassigning log level for HDCP failures
Date: Mon, 29 Oct 2018 15:15:47 +0530	[thread overview]
Message-ID: <1540806351-7137-3-git-send-email-ramalingam.c@intel.com> (raw)
In-Reply-To: <1540806351-7137-1-git-send-email-ramalingam.c@intel.com>

As a policy, this change considers all I915 programming failures and
HW failures as ERRORS. Where as all HDCP failures due to the sink is
considered as DEBUG logs.
