From: Arnd Bergmann <arnd@arndb.de>
The one-element array in aac_aifcmd is actually meant as a flexible array, and causes an overflow warning that can be avoided using the normal flex arrays:
drivers/scsi/aacraid/commsup.c:1166:17: error: array index 1 is past the end of the array (that has type 'u8[1]' (aka 'unsigned char[1]'), cast to '__le32 *' (aka 'unsigned int *')) [-Werror,-Warray-bounds] (((__le32 *)aifcmd->data)[1] == cpu_to_le32(3)); ^ ~
