From 3f224f4e057ce67713f3e7a8890f2fbe12d047a5 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 24 Sep 2010 04:04:26 +0900 Subject: sh: provide generic arch_debugfs_dir. While sh previously had its own debugfs root, there now exists a common arch_debugfs_dir prototype, so we switch everything over to that. Presumably once more architectures start making use of this we'll be able to just kill off the stub kdebugfs wrapper.
