From 024cfa5943a7e89565c60b612d698c2bfb3da66a Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Mon, 6 Sep 2010 13:52:01 +0300 Subject: usb: musb_debugfs: don't use the struct file private_data field with seq_files 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.
