	Sys/dev/pcmcia/pcmciadevs_data.h contains invalid c-code.
	There is two bugs in the awk code that generates the file. The
	first adds extra } at end of each product string. Second one
	generates fields in invalid order for those devices whose
	product id is not known.

	Also there is no definition of the pcmcia_knowndev structure

	It would also be better to export pcmciadevs.h,
	pcmciadevs_data.h, cardbusdevs.h and cardbusdevs_data.h, as
	they can be usefull in the usermode programs. I have a
	loadable kernel module (with ~20 line patch to pcmcia.c and
	cardbus.c) that will send card attach and detach notifications
	from kernel to user mode daemon. Currently the daemon only
	prints out debug info, but I plan to run suitable shell script
	when the card is attached/detached, so I can run ifconfig up /
	dhclient etc stuff there.

	The debugging info include the vendor and product names, thus
	I need the pcmciadevs_data.h and cardbusdevs_data.h files for

	kaakeli (6:12) ~>./cardwatchd
	pcmcia card wi0 attached to pcmcia0
	Manufacturer Lucent Technologies (0x156), product = WaveLAN/IEEE (0x2)
	pcmcia card wi0 detached
	pcmcia card ne0 attached to pcmcia0
	Manufacturer I-O DATA (0x1bf), product = I-O DATA PCLA/TE (0x2216)
	pcmcia card ne0 detached


	Try to compile following file:

	#include <stdio.h>
	#include <fcntl.h>
	#include <sys/param.h>
	#include <sys/proc.h>
	#include <sys/device.h>
	#include <dev/pcmcia/pcmciavar.h>
	struct pcmcia_knowndev {
	  int32_t vendor;
	  int32_t product;
	  struct {
	    const char *cis[4];
	  } cis;
	  int32_t flags;
	  const char *vendor_name;
	  const char *product_name;
	#include "pcmciadevs.h"
	#include "pcmciadevs_data.h"


	Here is patch:
