Most nand drivers don't set a parent device for the mtd-device. The result is that information in sysfs is missing (no folder device). Comparing the output of git grep mtd_device_parse_register drivers/mtd/nand/ with git grep parent drivers/mtd/nand/ | cut -f 1 | sort -u showed that this is a very common error. Looking at some of those drivers a common pattern is visible which I put into a new inline function to reduce source code size and to avoid future similiar errors.
