From 210b834a964c775387098bbc9e3836d3cd0e9b14 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 11 Apr 2013 02:32:46 +0100 Subject: [PATCH] h8300: 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.
