This driver is the very definition of bitrotting:
- Introduced in commit
  79a140932c776 ("[PATCH] mips: vR41xx updates")
  which is 2.6.11-rc3.

- Provides ->register_callback which was removed in commit
  7f316b033b36a ("[PATCH] pcmcia: remove socket register_callback")
  which is v2.6.14-rc3

- Uses INIT_WORK() with three arguments which was removed in commit
  65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead of context data")
  which is v2.6.20-rc1

- Provides ->inquire_socket and uses socket_cap_t which was removed in
  commit
  b7949fdacbe00 ("[PCMCIA] Remove inquire_socket")
  which is 2.5.72

- Provides ->get_io_map which was removed in commit
  d7de1b64a23b9 ("[PCMCIA] pcmcia-2: Remove get_io_map and get_mem_map socket methods.")
  which is 2.5.66

Remove VRC4173 CARDU from the tree because it never had the luck to be
successfully compiled. Let it finally find peace in byte heaven.

Andrew, are you okay with routing this via your tree?
Nobody responded to this and as I documented in the patch description it
never compiled so.

This driver is the very definition of bitrotting:
- Introduced in commit
  79a140932c776 ("[PATCH] mips: vR41xx updates")
  which is 2.6.11-rc3.

- Provides ->register_callback which was removed in commit
  7f316b033b36a ("[PATCH] pcmcia: remove socket register_callback")
  which is v2.6.14-rc3

- Uses INIT_WORK() with three arguments which was removed in commit
  65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead of context data")
  which is v2.6.20-rc1

- Provides ->inquire_socket and uses socket_cap_t which was removed in
  commit
  b7949fdacbe00 ("[PCMCIA] Remove inquire_socket")
  which is 2.5.72

- Provides ->get_io_map which was removed in commit
  d7de1b64a23b9 ("[PCMCIA] pcmcia-2: Remove get_io_map and get_mem_map socket methods.")
  which is 2.5.66

Remove VRC4173 CARDU from the tree because it never had the luck to be
successfully compiled. Let it finally find peace in byte heaven.
