- * linux/drivers/char/mouse.c
- *
- * Generic mouse open routine by Johan Myreen
- *
- * Based on code from Linus
- *
- * Teemu Rantanen's Microsoft Busmouse support and Derrick Cole's
- *   changes incorporated into 0.97pl4
- *   by Peter Cervasio (pete%q106fm.uucp@wupost.wustl.edu) (08SEP92)
- *   See busmouse.c for particulars.
- *
- * Made things a lot mode modular - easy to compile in just one or two
- * of the mouse drivers, as they are now completely independent. Linus.
- *
- * Support for loadable modules. 8-Sep-95 Philip Blundell <pjb27@cam.ac.uk>
- *
- * Fixed a failing symbol register to free the device registration
- *		Alan Cox <alan@lxorguk.ukuu.org.uk> 21-Jan-96
