    video: udlfb: Improve a size determination in dlfb_alloc_urb_list()
    
    Replace the specification of a data structure by a pointer dereference
    as the parameter for the operator "sizeof" to make the corresponding size
    determination a bit safer according to the Linux coding style convention.
    
    This issue was detected by using the Coccinelle software.
