Date:	Sat, 21 Nov 2015 18:28:05 +0100
From:	Julia Lawall <Julia.Lawall@...6.fr>
To:	"David S. Miller" <davem@...emloft.net>

Subject: [PATCH] net: atm: constify in_cache_ops and eg_cache_ops structures

The in_cache_ops and eg_cache_ops structures are never modified, so declare
them as const.

Done with the help of Coccinelle.
