drivers/atm: Use DIV_ROUND_UP
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:
