The `ni_tio_input_cmd()`, `ni_tio_output_cmd()` and `ni_tio_cmd_setup()`
functions are called from `ni_tio_cmd()` to set up a comedi command.
They currently get passed two parameters, a pointer to a `struct
ni_gpct` and a pointer to a `struct comedi_async`, but both of those
come from members of a `struct comedi_subdevice` (the former from the
`private` member).  Replace the parameters with a pointer to the `struct
comedi_subdevice`.

The main motive is to make the comedi subdevice more easily available to
the functions for the use of subsequent patches to remove the `struct
comedi_async *` parameters from the comedi buffer handling functions.

staging: slicoss: fix eeprom checksum code

Rewrite slic_eeprom_cksum() to fix bugs and make readable. This patch
technically has no effect on the user as failed eeprom checksums are
ignored anyway.

The original implementation had the following issues:

  1. 2 of the 3 unrolled loops had the following bug:

       while ((len -= 32) >= 0) {
               [...]
               sum += w[15];
               w = (u16 *)((ulong) w + 16);    /* verify */
       }

     This processes 32-bytes of data but only increments the word
     pointer by 16 bytes. Fixing both of these bugs seems to fix
     slic_eeprom_cksum().

  2. Non-descriptive variable names, use of unions, and macros that
     change local state make the code difficult to read.

  3. The checksum loop is unrolled which makes the code harder to
     reason about while providing small performance improvement:
      - max eeprom length is 0x80 bytes (MAX_EECODE_SIZE), that's
        only 0x40 iterations
      - checksum is only computed during pci probe(), so not very
        often

Tested on Mojave card

staging: slicoss: fix use-after-free bug in slic_entry_remove

This patch fixes a use-after-free bug that causes a null pointer
dereference in slic_entry_halt.

Since unregister_netdev() will ultimately call slic_entry_halt (the
net_device ndo_stop() virtual function for this device), we should
call it before freeing the memory used by slic_entry_halt.

staging: slicoss: fix 64-bit isr address bug

This patch fixes a bug that only manifests when the physical address of
the interrupt status register is >4GB. Specifically, the driver was only
telling the device about the lower 32 bits of the ISR. This patch adds
the upper 32 bits.

staging: slicoss: fix dma memory leak

This patch fixes a memory leak in slic_card_init. If the driver fails
to poll for an interrupt after requesting config data from the device
the dma memory is never freed.

staging: slicoss: remove gratuitous debug infrastructure

As per the TODO file, this patch removes the gratuitous debug
infrastructure. As an extra incentive for removing this code,
the debugfs files are not cleaned up properly. For example, if
register_netdev() fails in slic_entry_probe() then all debugfs
files get left behind, even after the driver module is unloaded.
Touching these files quickly leads to an oops.
