Well, maybe I missing something, but mtdchar.c:

static int mtd_open(struct inode *inode, struct file *file)
{
         int minor = MINOR(inode->i_rdev);
         int devnum = minor >> 1;
         struct mtd_info *mtd;

....

Notice "minor >> 1".

As far as I understand, even numbers are used for rw access, odd - for ro.
