*
* A PCMCIA client driver for the Raylink wireless LAN card.
* The starting point for this module was the skeleton.c in the
* PCMCIA 2.9.12 package written by David Hinds, dahinds@users.sourceforge.net
*
* Copyright (c) 1998 Corey Thomas (corey@world.std.com)
*
* Changes:
* Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 08/08/2000
* - reorganize kmallocs in ray_attach, checking all for failure
* and releasing the previous allocations if one fails
*
* Daniele Bellucci <bellucda@tiscali.it> - 07/10/2003
* - Audit copy_to_user in ioctl(SIOCGIWESSID)
