2 | * | |
3 | * A PCMCIA client driver for the Raylink wireless LAN card. | |
4 | * The starting point for this module was the skeleton.c in the | |
5 | * PCMCIA 2.9.12 package written by David Hinds, dahinds@users.sourceforge.net | |

22 | * | |
23 | * Changes: | |
24 | * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 08/08/2000 | |
25 | * - reorganize kmallocs in ray_attach, checking all for failure | |
26 | * and releasing the previous allocations if one fails | |
27 | * | |
28 | * Daniele Bellucci <bellucda@tiscali.it> - 07/10/2003 | |
29 | * - Audit copy_to_user in ioctl(SIOCGIWESSID) | |
