+Subject: [PATCH 2964/4131] drm/amd/display: remove redundant null check of
+ array 'data'
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The null check on aconnector->base.edid_blob_ptr->data is redundant
+since data is an array and can never be null.  Remove it.
+
+Detected by CoverityScan, CID#1460369 ("Array compared against 0")
