From: Stephen Boyd <sboyd@xxxxxxxxxxxxxx>
Subject: libfs: add simple_open()
debugfs and a few other drivers use an open-coded version of simple_open()
to pass a pointer from the file to the read/write file ops. Add support
for this simple case to libfs so that we can remove the many duplicate
copies of this simple function.
