This patch causes a problem.  It looks as though the firmware file may be
incorrectly built for at least 12160.  We get a checksum error from the
ISP12160 when it does the checksum:

qla1280 0001:00:03.0: firmware: using built-in firmware qlogic/12160.bin
qla1280_mailbox_command: Command failed, mailbox0 = 0x0007, mailbox_out0 = 0x4003, istatus = 0x6000
m0 4003, m1 b141, m2 5555, m3 aa55
m4 55aa, m5 a5a5, m6 5a5a, m7 2525
scsi(0): RISC checksum failed.
scsi(0): initialize: pci probe failed!
qla1x160: Failed to initialize adapter


>From qla1280_start_firmware():
        /* Verify checksum of loaded RISC code. */
        mb[0] = MBC_VERIFY_CHECKSUM;
        /* mb[1] = ql12_risc_code_addr01; */
        mb[1] = ha->fwstart;
        err = qla1280_mailbox_command(ha, BIT_1 | BIT_0, mb);
        if (err) {
                printk(KERN_ERR "scsi(%li): RISC checksum failed.\n", ha->host_no);
                return err;
        }
