Subject: [PATCH 4.9 002/206] iio: max44000: correct value in illuminance_integration_time_available

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Akinobu Mita <akinobu.mita@...il.com>

commit b4e8a0eb718749455601fa7b283febc42cca8957 upstream.

According to the datasheet, the shortest available integration time for
ALS ADC conversion is 1.5625ms but illuminance_integration_time_available
sysfs file shows wrong value.
