2015-10-13mtd: core: set some defaults when dev.parent is setFrans Klaver

2015-10-13mtd: core: tone down suggestion that dev.parent should be setFrans Klaver
add_mtd_device() has a comment suggesting that the caller should have set dev.parent. This is required to have the parent device symlink show up in sysfs, but not for proper operation of the mtd device itself. Currently we have five drivers registering mtd devices during module initialization, so they don't actually provide a parent device to link to. That means we cannot WARN_ON() here, as it would trigger false positives. Make the comment a bit less firm in its assertion that dev.parent should be set.

2015-10-11mtd: nand_bbt: set the smallest size of bbt tableSheng Yong
When using nandsim to simulate a 128K block nand with `overridesize = 1', the size of mtd device is too small (mtd_size = 4 * block_size) to get the right length of bbt. Then when creating bbt, kzmalloc() will return ZERO_SIZE_PTR. This causes a NULL pointer oops when scanning bbt.
