### Description

<!-- Explain what you did, what you expected to happen, and what actually happened. --> module: tm kemi proto relay functions fails on TLS: - ki_t_relay_to_proto - ki_t_relay_to_proto_addr

### Troubleshooting

#### Reproduction

<!-- If the issue can be reproduced, describe how it can be done. -->

#### Debugging Data

<!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location.

### Possible Solutions

<!-- If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix. --> It's missing an equal zero (== 0) on TLS test. Code: tm.c

if (strncasecmp(sproto->s, "UDP", 3) == 0) { proto = PROTO_UDP; } else if (strncasecmp(sproto->s, "TCP", 3) == 0) { proto = PROTO_TCP; } else if (strncasecmp(sproto->s, "TLS", 3)) { proto = PROTO_TLS; } else { LM_ERR("bad protocol specified <%s>\n", sproto->s); return E_UNSPEC; }

Fix:

if (strncasecmp(sproto->s, "UDP", 3) == 0) { proto = PROTO_UDP; } else if (strncasecmp(sproto->s, "TCP", 3) == 0) { proto = PROTO_TCP; } else if (strncasecmp(sproto->s, "TLS", 3) == 0) { proto = PROTO_TLS; } else { LM_ERR("bad protocol specified <%s>\n", sproto->s); return E_UNSPEC; }
