From 4bad78c550025346de3fc5820e366c7b525e1889 Mon Sep 17 00:00:00 2001 From: Rob Jones Date: Mon, 13 Oct 2014 15:51:32 -0700 Subject: lib/dynamic_debug.c: use seq_open_private() instead of seq_open() Using seq_open_private() removes boilerplate code from ddebug_proc_open(). The resultant code is shorter and easier to follow. This patch does not change any functionality.
