staging: comedi: fix memory leak for saved channel list
When `do_cmd_ioctl()` allocates memory for the kernel copy of a channel
list, it frees any previously allocated channel list in
`async->cmd.chanlist` and replaces it with the new one. However, if the
device is ever removed (or "detached") the cleanup code in
`cleanup_device()` in "drivers.c" does not free this memory so it is
lost.
A sensible place to free the kernel copy of the channel list is in
`do_become_nonbusy()` as at that point the comedi asynchronous command
associated with the channel list is no longer valid. Free the channel
list in `do_become_nonbusy()` instead of `do_cmd_ioctl()` and clear the
pointer to prevent it being freed more than once.
Note that `cleanup_device()` could be called at an inappropriate time
while the comedi device is open, but that's a separate bug not related
to this this patch.

staging: comedi: kcomedilib: fix a __user space access issue
The 'data' field in struct comedi_insn is an unsigned int __user *.
The comedi core copies this data to kernel space before passing it
on to a drivers insn_bits/insn_config method.
kcomedilib provides an interface for external kernel modules to
use the comedi drivers. This interface creates a comedi_insn
that is then passed to the comedi drivers insn_bits/insn_config
method. Unfortunately, kcomedilib is using the comedi_insn 'data'
field directly which results in some sparse warnings:
warning: incorrect type in argument 4 (different address spaces)

warning: incorrect type in assignment (different address spaces)

Fix this by passing the kernel data directly, as a separate parameter,
instead of trying to put in into the comedi_insn 'data' field. This is
how the comedi core handles the data from user space.

`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()`).

staging: comedi: fix sparse warning in do_devconfig_ioctl()
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

This does not work for auto-configured PCI devices due to the
firmware loading options not being set in the comedi_devconfig

Change the driver so it gets the firmware using request_firmware()

staging: comedi: comedi_fops: cast the cmd->chanlist to the correct address space
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.
