The dev->read_subdev used in this driver for async commands returns the
full scan with each sample so it should have the SDF_PACKED subdev_flag
set.
Add the missing subdev_flags and use comedi_buf_write_samples() to add
the sample to the async buffer.
The core sets the async events appropriately. Remove the unnecessary
event handling in the driver.
