+Subject: [PATCH] tee-supplicant: fix build with kernel < 4.16
+
+Commit 3ac968ee7c927271e83ea3a4247839649202ab5e moved linux/tee.h from
+libteec/include to libteec/src resulting in the following build failure
+with any kernel < 4.16 (i.e before

+
+To fix this build failure, update CMakeLists.txt and Makefile of
+tee-supplicant to add libteec/src to the include directories.
