Yes, you're right, and I think I didn't define correctly the maximum
value, I use 31 instead of 32 as explained in include/scsi/scsi_host.h:
/*
* These three parameters can be used to allow for wide scsi,
* and for host adapters that support multiple busses
* The last two should be set to 1 more than the actual max id
* or lun (e.g. 8 for SCSI parallel systems).
*/
unsigned int max_channel;
unsigned int max_id;
u64 max_lun;
