From 207e39099a90a7385900aca4868ed686f25300cb Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 8 Apr 2013 16:06:20 +0100 Subject: [PATCH] ft1000: Don't use create_proc_read_entry() Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead.
