7aa68dcce0 iio: proximity: sx9324: add empty line in front of bullet list
"make htmldocs" emits a warning of:

    Documentation/ABI/testing/sysfs-bus-iio-sx9324:2: WARNING: Unexpected indentation.

This is due to a missing empty line in front of the bullet list.
Fix it.

Note: The line count of 2 in the warning is not exact in this case.

4c18a890df iio:proximity:sx9324: Add SX9324 support
Semtech SAR sensor SX9324 is an evolution of the SX9310:
It has 4 phases that can be configured to capture and process data
from any of 3 CS pins and provide independent detection:
proximity, table proximity or body proximity.

Gather antenna data:
  echo sx9324-dev3 > trigger/current_trigger
  echo 1 > scan_elements/in_proximity0_en
  echo 1 > buffer/enable
  od -v -An --endian=big -t d2 -w2 /dev/iio\:device3
  (at 10Hz, the default).

Trigger events:
Setting:
  thresh_falling_period: 2 (events)
  thresh_rising_period: 2 (events)
  in_proximity0_thresh_either_value: 300
  in_proximity0_thresh_either_hysteresis: 72

using iio_event_monitor /dev/iio\:deviceX, approaching my hand to the
antenna pad, I see:
...
Event: time: 1634763907532035297, type: proximity, channel: 0, evtype:
thresh, direction: falling
Event: time: 1634763910138104640, type: proximity, channel: 0, evtype:
thresh, direction: rising
