Bagas Sanjaya ed81d3de8e Documentation: ad4130: format list of in_voltage-voltage_filter_mode_available modes 
Sphinx reports two warnings on sysfs documentation for AD4130 driver:

Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130:2: WARNING: Block quote ends without a blank line; unexpected unindent.

These are due to misformatting of sinc* modes list. Format it with bullet
list. Since each entry spans multiple lines, separate each with a blank
line.

What: /sys/bus/iio/devices/iio:deviceX/in_voltage-voltage_filter_mode_available KernelVersion: 6.2 Contact: linux-iio@vger.kernel.org Description: Reading returns a list with the possible filter modes.

	  * "sinc4"       - Sinc 4. Excellent noise performance. Long
                1st conversion time. No natural 50/60Hz rejection.

	  * "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion
	    time.

	  * "sinc3"	      - Sinc3. Moderate 1st conversion time.
	    Good noise performance.

	  * "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling
	    frequency of 50Hz, achieves simultaneous 50Hz and 60Hz
	    rejection.

	  * "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion
	    time. Best used with a sampling frequency of at least
	    216.19Hz.

	  * "sinc3+pf1"   - Sinc3 + Post Filter 1. 53dB rejection @
	    50Hz, 58dB rejection @ 60Hz.

	  * "sinc3+pf2"   - Sinc3 + Post Filter 2. 70dB rejection @
	    50Hz, 70dB rejection @ 60Hz.

	  * "sinc3+pf3"   - Sinc3 + Post Filter 3. 99dB rejection @
	    50Hz, 103dB rejection @ 60Hz.

	  * "sinc3+pf4"   - Sinc3 + Post Filter 4. 103dB rejection @
	    50Hz, 109dB rejection @ 60Hz.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY-voltageZ_filter_mode KernelVersion: 6.2 Contact: linux-iio@vger.kernel.org Description: Set the filter mode of the differential channel. When the filter mode changes, the in_voltageY-voltageZ_sampling_frequency and in_voltageY-voltageZ_sampling_frequency_available attributes might also change to accommodate the new filter mode. If the current sampling frequency is out of range for the new filter mode, the sampling frequency will be changed to the closest valid one.
