Commit cc5a71637 ("Replace key_scan array of static pointers with inline function")
has introduced get_key_scan() routine with switch statement which calls ASSERT
in certain case. Even though "this should never happen", this code triggers Level 1
warning "not all control paths return a value" in msvc.

Fix by adding "return NULL; /* NOTREACHED */"" after ASSERT.
