    Problem is : In normal path, kfree(inq_buff); is not called.

    It is called only if a "goto clean4;" is done (error path,
    and in this case, inq_buff is NULL anyway)

    So we exit from cciss_init_one() without freeing
    a "InquiryData_struct" structure.

    I am pretty sure kmemleak would complain on this leak :)
