Subject: [PATCH 2/2] drm/amd/dc: Kill dc_conn_log_hex_linux()
Date: Tue, 31 Mar 2020 17:22:24 -0400	[thread overview]
Message-ID: <20200331212228.139219-3-lyude@redhat.com> (raw)
In-Reply-To: <20200331212228.139219-1-lyude@redhat.com>

DRM already supports tracing DPCD transactions, there's no reason for
the existence of this function. Also, it prints one byte per-line which
is way too loud. So, just remove it.
