From 027f90073af54d394f629f4f091a316b26beec67 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Wed, 29 Dec 2010 11:42:13 -0800 Subject: [PATCH] datapath: Drop constness of datapath pointers. A few places marked struct datapath pointers as const since they didn't expect to make modifications. However, when compiled with lockdep the datapath mutex pointer is passed to lockdep_is_held(), which has a non-const argument. That provoked warnings about casting away the const, so this drops the const from the original pointers.
