There is a proposed change to the miscdevice's behaviour on open(). Currently file->private_data stays NULL, but only because we don't have an open-entry in struct file_operations. This may change so that private_data, more consistently, is always set to struct miscdevice, not only *if* the driver has it's own open() routine and fops-entry, see https://lkml.org/lkml/2014/12/4/939 and commit 94e4fe2c In short: If we rely on file->private_data being NULL, we should ensure it is NULL ourselves.
