[PATCH] mtd: nand: fix for drop unnecessary partition parser data

    Hi Brian,

    After merging the l2-mtd tree, today's linux-next build (powerpc
    ppc44x_defconfig) failed like this:

    drivers/mtd/nand/ndfc.c: In function 'ndfc_chip_init':
    drivers/mtd/nand/ndfc.c:177:2: error: 'ppdata' undeclared (first use in this function)
      ppdata.of_node = flash_np;
      ^

    Caused by commit

      a61ae81a1907 ("mtd: nand: drop unnecessary partition parser data")

The flash node is already correctly assigned using the new helper
(nand_set_flash_node()) so the correct fix is indeed to simply drop this
line.

Resending Stephen's report from here:

https://lkml.org/lkml/2015/12/21/6

so that it gets a look on the MTD list. I've added just a tiny bit of
commentary too.

I don't plan to rebase my tree to fix the bisectability, since this is buried
far enough under other things that should be kept stable.

FWIW, I've now added this driver to my build tests.
