I guess this is to strip "/dev/". Devtmpfs has no clue where it is
mounted, it is just a simple superblock.

I guess, the caller would better pass a relative path to it, to keep
all the implicit lookup magic with root=/dev/* in one place where the
commandline parsing and mounting happens? For the same reason
devtmpfs_mount() accepts a path instead of just assuming "/dev".
