Subject: [PATCH 5/7] drivers/atm/eni.c: ensure arguments to request_irq and free_irq are compatible

From: Julia Lawall <Julia.Lawall@...6.fr>

Convert call to request_irq so that the last argument is the same as the
second argument of the subsequent call to free_irq.  Without this
property, free_irq does nothing.

I have chosen to keep the call to free_irq as is, because its second
argument is more like its first argument.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>

Not tested.  I don't know if I have made the right choice.
