+Subject: gcov: add support for checksum field
+
+From: Rickard x Andersson <rickaran@axis.com>
+
+commit e96b95c2b7a63a454b6498e2df67aac14d046d13 upstream.
+
+In GCC version 12.1 a checksum field was added.
+
+This patch fixes a kernel crash occurring during boot when using
+gcov-kernel with GCC version 12.2.  The crash occurred on a system running
+on i.MX6SX.
+
