+Subject: [PATCH 1848/2940] drm/amd/display: fix incorrect null check on
+ pointer
+
+Currently an allocation is being made but the allocation failure
+check is being performed on another pointer. Fix this by checking
+the correct pointer. Also use the normal kernel idiom for null
+pointer checks.
+
+Addresses-Coverity: ("Resource leak")
+Fixes: 43e3ac8389ef ("drm/amd/display: Add function to copy DC streams")
