Shouldn't what the controller supports be compared with what the device supports,
e.g. as follows?

min_t(int, dev_info->rtt_cap, hba->vops->max_num_rtt ? : hba->nortt);

Hmm ... why 'int' instead of an unsigned type? If the type would be changed
into 'u8' (the type of rtt_cap) then the above min_t() can be changed into
min().

Thanks,

Bart.
