dmesg output

This is on the Kirkwood platform, running on a Sheevaplug.  
I first observed this problem with Linux 4.4.0.  Linux 4.3.4 works fine.

Kernel config for linux 4.4.1
Comment 2 nickkrause 2016-03-25 04:22:19 UTC
Try moving this line:
  mtd = nand_to_mtd(nc);
Below these two lines:
 nand_set_controller_data(nc, board)
 nand_set_flash_node(nc, pdev->dev.of_node);
for the function,  orion_nand_probe in the file, drivers/mtd/nand/orion_nand.c. The path I am stating is from the root directory of the kernel source tree.
Comment 3 Stuart Winter 2016-03-26 10:13:50 UTC
Hi Nick

I'm puzzled:

mozes@courgette:/tmp/linux-4.4.1$ grep -ri "nand_to_mtd" .
mozes@courgette:/tmp/linux-4.4.1$ grep -ri "nand_set_flash_node" .
mozes@courgette:/tmp/linux-4.4.1$

Which Kernel tree are you looking at? This is the virgin kernel from kernel.org.
Comment 4 nickkrause 2016-03-26 17:22:05 UTC
I am looking at 4.6 mainline but this is the function name you can try and grep for orion_nand_probe.
