As pointed out by the kbuild test robot, and Ian Abbott, the dma >= 0 test
is always true because dma is unsigned. This generates a warn message:

  warn: always true condition '(dma >= 0) => (0-u32max >= 0)'

Zsmalloc has two methods 1) copy-based and 2) pte based to
access objects that span two pages.
You can see history why we supported two approach from [1].

But it was bad choice that adding hard coding to select arch
which want to use pte based method because there are lots of
SoC in an architecure and they can have different cache size,
CPU speed and so on so it would be better to expose it to user
as selectable Kconfig option like Andrew Morton suggested.

No one seems to be working on it anymore, and it really should be merged
into the already-existing btusb driver.  Also, there is not any proper
author attribution on the code (it was copied from the in-kernel
driver...)

If someone wants to pick this back up, we can easily revert this, but
for now, delete the driver.

Clean up the local variables, 'sdev_no' and 'asic' are both used in
simple for () loops. Use the local variable 'i' for both cases. The
'n_subdevs' variable is only used in one place, just remove it.

For aesthetics, add some whitespace to the subdevice init and reorder
it to follow the more typical style in comedi drivers.

Remove the unnecessary init of s->len_chanlist for subdevices that do
not support async commands (interrupts). The core will default it to
the correct value.

This dio subdevice (*insn_bits) function does not follow the "norm"
for comedi drivers. It also _appears_ to return the incorrect state
of the channels.

Use the comedi_dio_update_state() helper to handle the boilerplate
for updating the output channel state. Due to the hardware we then
need to invert the state and mask the input channels before updating
the outputs.

Then read the hardware and invert the result to get the current true
state of the dio channels.
