+Fix segmentation fault for release build mode
+
+'int IAFBApi::callSync(...)' is missing a return
+statement. When the sdk is compiled in release mode
+executing this code results in a segmentation fault.
+
+According to the C++ standard, a return statement is
+required on a function that returns a non-void value.
+Specifically: <<Flowing off the end of a function is
+equivalent to a return with no value; this results in
+undefined behaviour in a value-returning function.>>
+
+The proposed fix provides the missing return statement
+for IAFBApi's callSync method.
+
+Upstream-Status: Pending
