[MiNT] Using device files in "/dev" from kernel space

Hi,

>From what I know in UNIX kernels files in /dev directory make an
interface between user space applications and device drivers.

Is correct to use this interface from kernel space? For example
opening a device and calling ioctl() or Fcntl() functions from a
kernel module.
Of course although this question could be apply to any UNIX kernel I'm
interested in what is correct under MiNT.

Thanks

David
