This driver does a lot of casting of smaller buffers to
a larger command response struct, GCC 12 does not like that:
drivers/net/wireless/marvell/libertas/cfg.c:1198:63: warning: array subscript ‘struct cmd_ds_802_11_associate_response[0]’ is partly outside array bounds of ‘unsigned char[203]’ [-Warray-bounds]
1198 | "aid 0x%04x\n", status, le16_to_cpu(resp->statuscode),
| ^~
Annoyingly it's not clever enough to recognize which fields
are safe to access, so move this warning to W=1 for now.
