The external callers of ni_tio_acknowledge_and_confirm() only call
this function to ack any pending errors or interrupts before starting
a new async command. Only the internal code in ni_tiocmd uses the
data that is optionally returned by this function.
Remove the export from ni_tio_acknowledge_and_confirm() and introduce
a new exported function that handles passing the NULL params.

The cmd->start_src is validated in the (*do_cmdtest) before this
function is called. All valid trigger sources are handled so the
default BUG() case can never occure.
For aesthetics, refactor the switch into if/else tests and remove
the BUG().
For aesthetics, rename the local variable 'retval' to simply 'ret'.

The 'enable' and 'read_not_write' parameters are true/false flags. For
aesthetics, change their types to bool.
Rename the local variable 'input_select_bits' to simply 'bits' and reuse
it when enabling the dma on the m series and 660x counter variants.
Add a local variable for the 'mask' that is passed to ni_tio_set_bits()
to help clarify the code.

The "amplc_pc236" driver currently handles both ISA and PCI devices and
uses a small amount of conditional compilation depending which are
enabled.
Move most of the functionality into a new module, "amplc_pc236_common",
and split off support for PCI devices into a new module, "amplc_pci236".
Retain support for ISA devices in the existing module, "amplc_pc236".
Since the `detach` handler (`pc236_detach()`) in the existing module
"amplc_pc236" now only needs to handle ISA devices and only calls
`comedi_legacy_detach()`, just use `comedi_legacy_detach()` directly as
the `detach` handler in `struct comedi_driver amplc_pc236_driver`.

If an asynchronous command was running when the device is being
detached, the comedi core would have called the subdevice `cancel`
handler (`pc236_intr_cancel()`) before calling the `detach` handler
(`pc236_detach()`). Since the cancel handler disables hardware
interrupts (at least for the PCI236 board) by calling
`pc236_disable_intr()`, there is no need for the detach handler to do so
as well. Remove the call to `pc236_disable_intr()` from
`pc236_detach()`.

dio200_pci_detach()
`dio200_pci_detach()` doesn't need to check if the pointer to constant
board data (`thisboard`) and the pointer to private per-device data
(`devpriv`) are valid before calling `amplc_dio200_common_detach()`. It
has no further need to check `thisboard` so remove the variable
altogether. Move the test of `devpriv` to the first point it is needs
to be valid.

amplc_dio200_common_detach()
`amplc_dio200_common_detach()` doesn't do much apart from freeing the
IRQ handler that was requested by `amplc_dio200_common_attach()` if
`dev->irq` is non-zero. There is no need to check if the pointer to
the constant board data or the pointer to private per-device data
exist, so remove those tests.

`dio200_detach()` in "amplc_dio200.c" calls
`amplc_dio200_common_detach()` in "amplc_dio200_common.c", followed by
`comedi_legacy_detach()` in "../drivers.c". Both of those functions
call `free_irq()` if `dev->irq` is non-zero. The second call produces a
warning message because the handler has already been freed. Prevent
that by setting `dev->irq = 0` in `amplc_dio200_common_detach()`.

The bug can be reproduced by using a format that do not have the width.prec
specified after a format that have the width.prec specified. The second

This patch fixes this issue. BZ 1094. Reported by Yizhe Wang, fixed by

Since acpi_ut_vprintf() is only enabled for specific OSPM now, this patch
