+Subject: [PATCH] test: fix usage of FILE in unit test fapi-io
+
+The unit test had a static FILE structure used to pass to stdio FILE *
+routines as a dummy value to indicate to use the __real_xxx variant of
+the mocked function. This doesn't work when FILE is opaque as the
+compiler cannot figure out how much storage space is needed for a FILE
+struct.
+
+Fix this by passing a dummy pointer to a data type the compiler knows
+about and casting it to FILE pointer.
+
+Fixes: #2419
