Subject[01/80] usb: musb_debugfs: dont use the struct file private_data field with seq_files
2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Mathias Nyman <mathias.nyman@nokia.com>

commit 024cfa5943a7e89565c60b612d698c2bfb3da66a upstream.

seq_files use the private_data field of a file struct for storing a seq_file structure,
data should be stored in seq_file's own private field (e.g. file->private_data->private)
Otherwise seq_release() will free the private data when the file is closed.
