When the Comedi "detach" handler is called, it is possible that an extra A/D conversion (triggered during termination of a Comedi asynchronous command) is still in progress. In that case, the FINISH bit in the Status register will eventually get set and there will be stale data waiting to be read from the A/D Data register. The interrupt handler will also be called if still connected at the time. That should all be mostly harmless, but it would be better to wait for any such conversion to complete and clear any stale data during the "detach". Add a custom "detach" handler `dt2814_detach()` to do that if an interrupt handler has been set up. (There is no need to do it if no interrupt handler was set up because Comedi asynchronous command support is disabled in that case.) Signed-off-by:

The `ntrig` member of the `struct dt2814_private` pointed to by `dev->private` is no longer used as a counter to determine the end of acquisition for a Comedi asynchronous command. The other member `curadscan` is also unused. Remove the allocation of the private data during initialization and remove the definition of `struct dt2814_private` since they are no longer needed.

The support for asynchronous commands in this driver is currently broken. If interrupts are enabled, the interrupt handler is called at the end of every A/D conversion. A/D conversions could be due to software-triggered conversions resulting from Comedi `INSN_READ` instruction handling, or due to timer-trigger conversions enabled when a Comedi asynchronous command is set up. We only want the interrupt handler to read a sample from the A/D Data register for timer-triggered conversions, but currently it always reads the A/D Data register. Since the A/D Data register is read twice (to read a 12-bit value from an 8-bit register), that probably interferes with the reading for software-triggered conversions. The interrupt handler does not currently do anything with the data, it just ignores it. It should be written to the Comedi buffer if handling an asynchronous command. Other problems are that the driver has no Comedi `cancel` handler to call when the asynchronous command is being stopped manually, and it does not handle "infinite" acquisitions (when the command's `stop_src == TRIG_NONE`) properly. Change the interrupt handler to check the timer enable (ENB) bit to check the asynchronous command is active and return early if not enabled. Also check the error (ERR) and "conversion complete" (FINISH) bits, and return early if neither is set. Then the sample can be read from the A/D Data register to clear the ERR and FINISH bits. If the ERR bit was set, terminate the acquisition with an error, otherwise write the data to the Comedi buffer and check for end of acquisition. Replace the current check for end of acquisition, using the count of completed scans in `scans_done` (updated by calls to `comedi_buf_write_samples()`) when `stop_src == TRIG_COUNT`) and allowing "infinite" acquisitions when `stop_src == TRIG_NONE`. Add a `cancel` handler function `dt2814_ai_cancel()` that will be called when the end of acquisition event is processed and when the acquisition is stopped manually. It turns off the timer enable (ENB) bit in the Control register, leaving the current channel selected. Signed-off-by:

The Comedi "attach" handler `dt2814_attach()` writes to the Control register to turn off the timer enable 'ENB' bit, which triggers a conversion. It then sleeps awhile and checks the Status register, returning an error if the ERR bit is set. However, the ERR bit could have been set due to the conversion being triggered while the A/D converter was busy (unlikely) or due to the conversion being triggered before some previous sample had been read from the A/D Data register. Replace the existing code with a call to `dt2814_ai_clear()` which waits for any conversion to finish and then clears any unread data or error condition. A non-zero return value from `dt2814_ai_clear()` indicates a time-out while waiting for the A/D converter to become non-busy. Return an error in that case. Signed-off-by:

When the interrupt handler decides the final sample has been acquired, it turns off the timer enable (ENB) bit in the Command register. That triggers another A/D conversion. The interrupt handler currently waits for that to finish and then reads the resulting, unwanted sample. Since the functions for handling Comedi read instructions and for setting up asynchronous commands now call `dt2814_ai_clear()` to wait for and discard any spurious A/D conversion, let's remove that code from the interrupt handler.

When performing a Comedi read instruction or setting up an asynchronous command on the AI subdevice, clear any stale data on the A/D registers by waiting for the Status register's BUSY bit to clear (if set) and then if the FINISH or ERR bit is set, reading the A/D Data register twice to clear the stale data.
