    drivers/atm: Use DIV_ROUND_UP · 6a19309d
    Julia Lawall authored
    The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /
    (d)) but is perhaps more readable.
    
    In the case of the file drivers/atm/eni.c, I am a little bit suspicious of
    the -1 at the end of the affected expression.  Please check that that is
    what is wanted.
    
    An extract of the semantic patch that makes this change is as follows:
