+From cc9589c03cb0fcd9c3248b95f05cce1afaa37d0f Mon Sep 17 00:00:00 2001
+From: Balint Dobszay <balint.dobszay@arm.com>

+Subject: [PATCH] Remove TEE driver external component
+
+The TSTEE driver has been merged to Linux kernel v6.10, which makes the
+out-of-tree version deprecated. Remove the external component that was
+downloading it. Also, the in-tree version doesn't have a module version
+field defined, so the sanity check for reading the out-of-tree module's
+version is removed too.
+
+Signed-off-by: Balint Dobszay <balint.dobszay@arm.com>
