The comedi async commands should stop if an error/overflow happens or when
the end-of-acquisition for the command is detected. Some of the drivers
do this correctly but many don't.
The comedi_handle_events() function automatically detects the events that
would terminate a command. If the events are set it calls the subdevice
(*cancel) operation to stop the command.
Convert the drivers to use comedi_handle_events() instead of
comedi_event().
This allows removing the unnecessary cancel in the driver, if present, and
ensures that all the drivers terminate the commands if necessary.
The only drivers that still use comedi_event() are the usbdux drivers.
These
have a "cancel" in the urb completion routines that does not do what the
(*cancel) does. I'm waiting for a reply from the author to see if this can
be changed.
