[PATCH 2/6] libmachdev: remove mach_device_deallocate

[Justus Winter]

mach_device_deallocate just called ports_port_deref.  However, the
reference counting is done by the translation functions, explicitly
reducing the reference count is just wrong.

* libmachdev/ds_routines.c (mach_device_deallocate): Remove now unused
function.
(ds_device_close): Drop spurious call to mach_device_deallocate.
