|
|
* 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)
