+Subject: [PATCH] display: cirrus: ignore source pitch value as needed in
+ blit_is_unsafe
+
+Commit 4299b90 added a check which is too broad, given that the source
+pitch value is not required to be initialized for solid fill operations.
+This patch refines the blit_is_unsafe() check to ignore source pitch in
+that case. After applying the above commit as a security patch, we
+noticed the SLES 11 SP4 guest gui failed to initialize properly.
