[PATCH net-next resend 10/13] debugfs: constify argument to debugfs_real_fops()

From: Jakub Kicinski
Date: Thu Nov 03 2016 - 13:12:36 EST


seq_file users can only access const version of file pointer,
because the ->file member of struct seq_operations is marked
as such. Make parameter to debugfs_real_fops() const.
