The following warning is seen when building netlink-dumps. netlink-dumps.c: In function ‘dump_extack’: ../kselftest_harness.h:788:35: warning: ‘ret’ may be used uninitialized
Problem is that the loop which initializes 'ret' may exit early without initializing the variable if recv() returns an error. Always initialize 'ret' to solve the problem.
