The variable user in struct iscsi_url is a character array, not a pointer.
Therefore its address will never be NULL.
When libscsi is built using clang instead of gcc, those errors are reported:
iscsi-perf.c:256:17: error:
comparison of array 'iscsi_url->user' not equal to a null
pointer is always true [-Werror,-Wtautological-pointer-compare]
iscsi-dd.c:272:17: error:
comparison of array 'iscsi_url->user' not equal to a null
pointer is always true [-Werror,-Wtautological-pointer-compare]
iscsi-dd.c:331:17: error:
comparison of array 'iscsi_url->user' not equal to a null
pointer is always true [-Werror,-Wtautological-pointer-compare]
ld_iscsi.c:99:18: error:
comparison of array 'iscsi_url->user' not equal to a null
pointer is always true [-Werror,-Wtautological-pointer-compare]
Fix those errors and also similar code patterns in aros/iscsi-ls.c and
test-tool/iscsi-support.c.
