Kernel config for linux 4.4.1
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. 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. I am looking at 4.6 mainline but this is the function name you can try and grep for orion_nand_probe. |
