Subject[PATCH 2.6.20] isdn-eicon: Use ARRAY_SIZE macro when appropriate
From
Hi all,

A patch to use ARRAY_SIZE macro already defined in kernel.h

Signed-off-by: Ahmed S. Darwish <darwish.07@gmail.com>
---
Also remove the macro
`#define DIM(array) (sizeof (array)/sizeof ((array)[0]))'
that reimplements ARRAY_SIZE. Encourage new code to use ARRAY_SIZE ;).
