I'd do like this:

rm -rf linux-2.6.15/drivers/mtd
cp -r linux-latest/drivers/mtd linux-2.6.15/drivers/

rm linux-2.6.15/include/mtd
cp -r linux-latest/include/mtd linux-2.6.15/include/mtd

rm linux-2.6.15/include/linux/mtd
cp -r linux-latest/include/linux/mtd linux-2.6.15/include/linux/mtd

Then try to compile & run and resolve all problems. I suspect there are 
not going to be many of them.
