[LTP] [PATCH] fix rpc_suite/rpc:add check returned value

[James Dong (董世江)]

Hi Petr

My test environment is centos8.2, kernel version is 4.18 (CentOS-8.2.2004-x86_64-dvd1.iso)
For example:
	svcr = svcfd_create(fd, 0, 0);
	//Then call destroy macro
	svc_destroy(svcr);

If "svcfd_create" fails, that is, the return value is NULL and then call "svc_destroy" will report an error "Segmentation fault"

Kind regards,
Dong

Hi Dong,

Sure this fix can get in. I saw issues with some tests on openSUSE, but that's a separate problem (I was not able to find the problem thus report it.

IMHO casting is not required, right? Just
	if (svcr == NULL) {

Kind regards,
