2.6.x nettel.c compile problems

["Brian T" <btuch@usa.net>]

Sorry if this was covered, but I didn't see anything when searching.  I'm
trying to get the 2.6.2 kernel working with JFFS2 and MTD (Snapgear/Intel
chipset).  The standard ~/mtd/maps/nettel.c gave me an error when compiling,
so I patched to the CVS from 6/30, but I was still getting the same error :

  CC      drivers/mtd/maps/nettel.o
drivers/mtd/maps/nettel.c: In function `nettel_init':
drivers/mtd/maps/nettel.c:429: error: `ROOT_DEV' undeclared (first use in
this function)
drivers/mtd/maps/nettel.c:429: error: (Each undeclared identifier is
reported only once
drivers/mtd/maps/nettel.c:429: error: for each function it appears in.)
drivers/mtd/maps/nettel.c:429: warning: implicit declaration of function
`MKDEV'
make[3]: *** [drivers/mtd/maps/nettel.o] Error 1
make[2]: *** [drivers/mtd/maps] Error 2
make[1]: *** [drivers/mtd] Error 2
make: *** [drivers] Error 2

If I add this to the top of nettel.c ...

#ifndef CONFIG_BLK_DEV_INITRD
#include <linux/config.h>
#include <linux/fs.h>
#include <linux/major.h>
#include <linux/root_dev.h>
#endif

...then it compiles fine, but when booting the kernel it is unable to mount

I also tried enabling INITRD without the headers I added at the top, but
with the same result.

Any ideas on this?

Thanks,
