Recent changes in the module : http://www.redhat.com/archives/libvir-list/2014-June/msg00978.html seem to have caused Coverity to "take a look"... The virDomainCCWAddressAsString() API returns either a NULL or a string and the comparison of the returned value to "< 0" caused following errors: [1] CONSTANT_EXPRESSION_RESULT (1) Event result_independent_of_operands: "!(addr = virDomainCCWAddressAsString(&addrs->next)) < 0" is always false regardless of the values of its operands. This occurs as the logical operand of if. and 2] DEADCODE (1) Event between: At condition "!(addr = virDomainCCWAddressAsString(&addrs->next)) < 0", the value of "addr = virDomainCCWAddressAsString(&addrs->next)" must be between 0 and 1.
