Subject: [PATCH] net/socket/getsockname.c: Fix addrlen check in socket debug
 features.  Getsockname checked erroneously a pointer agains 0, where the
 intention was to dereference the pointer and to check the length.  This
 causes also a compilation failure if the code is compiled with
 CONFIG_DEBUG_FEATURES and with -Werror flag set.
