-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jiri Slaby <[email protected]>
patch ac6aec2f5683588361ab408cb3346b08c66bdfbe in mainline.
- register_device unconditionally (non-pci dependent) to have also isa
devices in /dev
- unregister devices on module removal
- don't set TTY_DRIVER_DYNAMIC_DEV twice (removed the one dependent on some
macro)
This is the substantial part of the patch and the previous point is for
not checking which devices to unregister and which not (simply register
and unregister all found no matter on which bus they are plugged).
