Replace OBD_CPT_ALLOC, OBD_CPT_ALLOC_PTR, and OBD_CPT_ALLOC_GFP by
corresponding calls to kzalloc_node. The semantic patch for the
OBD_CPT_ALLOC case is as follows: (http://coccinelle.lip6.fr/).
// <smpl>
@@ expression ptr,cptab,cpt,size; @@
- OBD_CPT_ALLOC(ptr, cptab, cpt, size)
+ ptr = kzalloc_node(size, GFP_NOFS, cfs_cpt_spread_node(cptab, cpt))
// </smpl>
Note that the original OBD macros would check if the cptab argument was
NULL and fall back on kzalloc in that case. Oleg Drokin argues that this
test is not needed because the code containing these calls is only invoked
after initialization has been completed, in which case the possible cptab
arguments are not NULL.

In the first case, llss can never be null at the point of the kfree anyway.
In the second set of changes, the gotos are either eliminated, when no
freeing is needed (hss failure case), or rewritten so that there is no call
to free on data that has not yet been allocated (free_hss goto case).
There is no goto at which attr is not null, so the out label is simply
dropped.

The `COMEDI_SRF_FREE_SPRIV` flag in the `runflags` member of `struct
comedi_subdevice` indicates that the memory pointed to by the `private`
member can be automatically freed by the comedi core on subdevice
clean-up (when the low-level comedi device is being "detached"). the
flag doesn't really belong in `runflags`, but it was somewhere
convenient to keep it without having to add a new member to the
structure.
Rather than access the `COMEDI_SRF_FREE_SPRIV` flag directly, use some
new wrapper functions:
* comedi_can_auto_free_spriv(s) - checks whether the subdevice's
`s->private` points to memory that can be freed automatically.
* comedi_set_spriv_auto_free(s) - marks the subdevice as having a
`s->private` that points to memory that can be freed automatically.
Export `comedi_set_spriv_auto_free()` for use by the low-level comedi
driver modules, in particular the "amplc_dio200_common" module.

serial2002_setup_subdevices() initializes each subdevice based on the
config read from the attached serial device. Part of this initialization
is to setup the subdevice range_table_list for the non digital subdevices.
The range_table_list is allocated only when a 'range' is passed to the
functions. Each channel of the subdevice then has it's 'range' initialized
and that range is added to the range_table_list.
The logic of this function works but causes Coverity complain about an
Explicit null dereference of the allocated 'range_table_list'. Add a check
for the 'range_table_list' to quiet the Coverity issue.
