Vadim Yanitskiy gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/7123 libbsc/bsc_vty.c: prevent uninitialized access If an out of range 'Last Valid Block' value for 'smscb-command' is passed, a 'last_block' of the 'rsl_ie_cb_cmd_type' struct could be uninitialized. Let's prevent this. Found using Clang Static Analyzer.
