/*============================================================================= |
|
* |
|
* 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, [email protected] |
|
* |
|
* Copyright (c) 1998 Corey Thomas ([email protected]) |
|
* |
|
* Changes: |
|
* Arnaldo Carvalho de Melo <[email protected]> - 08/08/2000 |
|
* - reorganize kmallocs in ray_attach, checking all for failure |
|
* and releasing the previous allocations if one fails |
|
* |
|
* Daniele Bellucci <[email protected]> - 07/10/2003 |
|
* - Audit copy_to_user in ioctl(SIOCGIWESSID) |
