Subject: [patch 05/11] atm: fix const assignment/discard warnings in the ATM networking driver

From: [email-masked]
Date: Wed, 30 Jul 2008 12:37:37 -0700

From: David Howells <[email-masked]>

Fix const assignment/discard warnings in the ATM networking driver.

The lane2_assoc_ind() function needed its arguments changing to match changes
in the lane2_ops struct (patch 61c33e012964ce358b42d2a1e9cd309af5dab02b).
