Subject[PATCH v4 09/17] dyndbg: prefer declarative init in caller, to memset in callee
Date
ddebug_exec_query declares an auto var, and passes it to
ddebug_parse_query, which memsets it before using it. Drop that
memset, instead initialize the variable in the caller; let the
compiler decide how to do it.
