+ *
+ * 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

+ * 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)
