mtd_blkdevs: don't scan partitions for plain mtdblock
mtdblock / mtdblock_ro set part_bits to 0 and thus nevever scanned partitions. Restore that behavior by setting the GENHD_FL_NO_PART flag. Fixes: 1ebe2e5f9d68e94c ("block: remove GENHD_FL_EXT_DEVT") Reported-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Christoph Hellwig <hch@lst.de> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20211206070409.2836165-1-hch@lst.de Signed-off-by: Jens Axboe <axboe@kernel.dk>
