staging: comedi: ii_pci20kc: cleanup final pieces

Tidy up the multi-line comments at the beginning of the file and
remove any irrelevant information.

Fix the II20K_ID_PCI200341M_1 define, there are one to many 0's.

Rename all the remaining pci20xxx_* to ii20k_*. The "pci" just adds
confusion, this is not a PCI board.

staging: comedi: ii_pci20kc: cleanup the ai subdevice

The PCI-200341M-1 module can both provide an analog input subdevice
in this driver. The module provides four differential input channels
with four programmable gains.

Currently the gain is configured as an option passed when the board
is attached. Rewrite the ai subdevice support functions to properly
handle the programmable gain.

For aesthetics, redefine the memory map for the module.

The PCI-20006M-1 and PCI-20006M-2 modules can both provide an
analog output subdevice in this driver. Fix the module init code
to detect both of them.

The analog output can support +/-5, 0-10, or +/-10 volt ranges
depending on jumpers on the board. Report all the ranges to the
user instead of relying on the configuration options to set the
range. The user can then select the appropriate range depending
on how they have configured the hardware.

Tidy up the (*insn_{read,write})() functions to work like the
comedi core expects.

staging/lustre/obdclass: use a dummy structure for lu_ref_link

Move the definition of struct lu_ref_link to lu_ref.h.  If USE_LU_REF
is not defined then define it to be the empty struct.  Change the
return type of lu_ref_add() and lu_ref_add_atomic() to void.  Add
lu_ref_add_at() taking same arguments as lu_ref_add() togerther with a
pointer to a struct lu_ref_link and returning void.  Adjust all
structures containing a lu_ref_link pointer to contain a struct
lu_ref_link instead.  Use lu_ref_add_at() and lu_ref_del_at() to
handle embedded lu_ref_links.

[Original patch mainly changes lu_ref.[ch] but in upstream client we don't
have lu_ref code in the hope of moving to kobject refcounting. So the patch
only picks the other pieces of original patch, in order to keep code in
sync and make it easier to port future patches.]
