[PATCH] Array overrun in drivers/net/wireless/wavelan.c
hi, this is another array overrun spotted by coverity (#id 507) we should check the index against array size before using it. Not sure why the driver doesnt use ARRAY_SIZE instead of its own macro. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>
