[lwip-users] Possible errors

[Fabian Cenedese]

Hi

There are a few places where variables are used without
checking (1) or even in case of NULL (2). I don't know if
the (1) errors really can occur but the code could check
anyway.

(1)
[lwip\src\api\api_msg.c:225] -> [lwip\src\api\api_msg.c:227]: (error) Possible 
null pointer dereference: conn - otherwise it is redundant to check it against 
null.
[lwip\src\api\api_msg.c:320] -> [lwip\src\api\api_msg.c:326]: (error) Possible 
null pointer dereference: conn - otherwise it is redundant to check it against 
null.
[lwip\src\api\api_msg.c:322] -> [lwip\src\api\api_msg.c:326]: (error) Possible 
null pointer dereference: conn - otherwise it is redundant to check it against 
null.

(2)
[lwip\src\core\ipv4\igmp.c:801]: (error) Possible null pointer dereference: igmp
