* gsm29118: fix coverity issuesPhilipp Maier2019-01-181-1/+6
| | | | | | | | | | | | | The function msgb_sgsap_name_put() assignes the return code of osmo_apn_from_str() directly to len. Len is an uint8_t and the return code an int. If osmo_apn_from_str() returns -1. Len would become 0xFF causing a buffer overrun with msgb_tlv_put. Lets use the proper type to catch the return code and check it before using it as length.
