This patch removes typedef for _stIM_sfHostNotify,
changes the name of the struct from
_stIM_sfHostNotify to bcm_stim_sfhostnotify.
In addition, any calls to the following typedef
"stIM_sfHostNotify" are changed to call the
struct directly.

the dc_init_descriptor_list actually returns a +ve error return codes,
which is abnormal as other functions in kernel return -ve error codes on
failure. so replace the return codes of this function with -ve values
to make the consistency with the other functions in kernel.
Also make the dc_init_descriptor_list static as its never called
anywhere except in this file and move the function prototype from the
headerfile into the c file as its referred only in this c file.

`parse_insn()` is dereferencing the user-space pointer `insn->data`
directly when handling the `INSN_INTTRIG` comedi instruction. It
shouldn't be using `insn->data` at all; it should be using the separate
`data` pointer passed to the function. Fix it.

`insn_rw_emulate_bits()` is used to emulate the `INSN_READ` and
`INSN_WRITE` comedi instructions for subdevices that don't have an
`insn_read()` or `insn_write()` handler but do have an `insn_bits()`
handler.
The function fills in a temporary `struct comedi_insn` called `new_insn`
to pass to the subdevice's `insn_bits()` handler. In doing so, it sets
the `new_insn.data` pointer to point to a temporary data array. This
results in a warning from "sparse" because the `data` pointer in `struct
comedi_insn` has the `__user` tag. The subdevice's `insn_bits()`
handler ignores it anyway as it gets passed a pointer to the temporary
data array in a separate parameter. Don't bother setting
`new_insn.data`; just leave it set to `NULL` (done by an earlier
`memset()`).

For the COMEDI_DEVCONFIG ioctl, the user application may embed a pointer
to firmware data within a designated element (or two elements for 64-bit
pointers) of the `options[]` array in the `struct comedi_devconfig`.
`do_devconfig_ioctl()` calls `comedi_aux_data()` to extract the pointer
value. It needs to be treated as a `__user` pointer so the firmware
data can be copied into kernel memory, so cast the result of
`comedi_aux_data()` to avoid a "sparse" warning. This is not ideal but
`comedi_aux_data()` is called elsewhere in a wholly kernel memory
context so we can't just change its return type to include the `__user`
tag.

This driver requires loading a firmware file for the cpld. This
is currently being done by passing the firmware data using the
COMEDI_DEVCONFIG ioctl through the attach() hook in the driver.
This does not work for auto-configured PCI devices due to the
firmware loading options not being set in the comedi_devconfig
parameter passed to the driver.
Change the driver so it gets the firmware using request_firmware()
and ignore any firmware options passed in the comedi_devconfig.

In this driver the PCI bar 2 resource is being ioremap'ed to a
void * in the private data. This void * is then being cast to a
struct daqboard2000_hw * that defines all the registers used by
the driver.
This is causing a number of sparse warnings similar to:
warning: incorrect type in argument 1 (different address space)
expected void const volatile [noderef] <asn:2>*addr
got void *
Change the type in the private data to void __iomem * to correctly
store the ioremap'ed address.

for the register memory map.

Rename 'chanlist_saver' to 'user_chanlist' to avoid confusion that
it's actually a __user *.
The chanlist pointer in comedi_cmd is still a user space pointer when
the comedi_cmd is copied with copy_from_user() in do_cmd_ioctl() and
do_cmdtest_ioctl(). This pointer needs to be cast when it is saved in
user_chanlist in order to preserve its address space.
The copy_from_user() call to copy the chanlist to the kernel space
comedi_command requires the second parameter to be a __user pointer.
Use the correctly cast user_chanlist instead of cmd->chanlist.
Before the comedi_cmd is copied back to user space, the saved
user_chanlist pointer is restored. Cast the user_chanlist again so
that the address space matches the comedi_cmd.

The 'chanlist' is passed to the kernel from user space with the
COMEDI_CMD and COMEDI_CMDTEST ioctls. The do_cmd_ioctl() and
do_cmdtest_ioctl() functions in comedi_fops.c copy this data
to/from user space to kernel space correctly.
Unfortunately, this data is copied back into a struct comedi_cmd
so when the cmd is passed down to the drivers they still see the
pointer as __user data. This results is a number of sparse errors
such as:
warning: dereference of noderef expression
warning: incorrect type in argument 2 (different address spaces)
expected void const *<noident>
got unsigned int [noderef] <asn:1>*chanlist
warning: incorrect type in argument 3 (different address spaces)
expected unsigned int *chanlist
got unsigned int [noderef] <asn:1>*chanlist
warning: incorrect type in assignment (different address spaces)
expected unsigned int *ai_chanlist
got unsigned int [noderef] <asn:1>*chanlist
The two functions in comedi_fops are the only ones that need the
__user tag. Remove the tag so that all the drivers see the chanlist
pointer in the correct address space.
