-Subject: [PATCH 1/5] 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.
