+Subject: PATCH fix missing mutex unlock
+
+Fixes a missing mutex unlock on an out of memory error
+in ltc_ecc_fp_save_state().
+
+Originates from: https://github.com/OP-TEE/optee_os/commit/4af447d4084e293800d4e463d65003c016b91f29
+
+Fixes #571
+
+Comment by sj:
+This patch version slightly deviates from the original patch to OP-TEE
+since we don't call `XFREE(NULL)` as there exist implementations of
+`free()` that don't support it.
