These are not used by iwl and copying these\nover overflows the iwl_keyinfo.key field.\n\nAdd a check to not copy more data to iwl_keyinfo.key then will fit.\n\nThis fixes backtraces like this one:\n\n memcpy: detected field-spanning write (size 32) of single field \"sta_cmd.key.key\" at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 (size 16)\n WARNING: CPU: 1 PID: 946 at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 iwlagn_send_sta_key+0x375/0x390 [iwldvm]\n <snip>\n Hardware name: Dell Inc.
