needed anymore.

4dd1944ab7 staging: tidspbridge - rename bridge_brd_mem_map/unmap to a proper name
Now these functions only map user space addresses to dsp virtual
addresses, so now the functions have a more meaningful name.
Also now user_to_dsp_map returns the mapped address.

e8184e6c2d staging: tidspbridge: Remove cfg_get_dev_object() and do a trivial cleanup
The cfg_get_dev_object function is only used in one place and because of
its simplicity, it can be removed.

The parameter *value can be left uninitialized if the strcmp() returns a
nonzero value, so in the function dev_remove_device(), the hdev_obj could
be used uninitialized and could be dereferenced in dev_destroy_device().
This patch fixes this issue, and also removes the dev_obj pointer which
is not used.
