Subject: [PATCH 3/7] staging: iio: isl29028: fix incorrect sampling frequency value

The sysfs attribute in_proximity_sampling_frequency_available currently
shows the values 1 3 5 10 13 20 83 100. These values are supposed to
correspond to the sleep values 800 400 200 100 75 50 12 0 (all in ms).
When passing in a sampling frequency of 3, it actually uses a sleep
time of 200ms instead of the expected 400ms value. This patch changes
the 3 supported sampling frequency to 2 so that the proximity sleep
time of 400ms can be used.
