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 cfc_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 all the drivers that still use comedi_event() to use cfc_handle_events() instead. 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() directly 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.
