I have not found a reasonable way to find an address of the
misc-device structure in the driver file operations.
inode->i_cdev is not pointing to the correct place due to way how
misc driver class is implemented - or I have totally missed something.
In misc open, information is available but it is not passed to the
driver itself. Privatedata field of the file struct passes now
pointer to the driver open function. Driver can do what ever needed
with that information.
