From: Martin Kelly Date: Sat, 2 Feb 2019 21:56:00 +0000 (-0800) Subject: iio:bmi160: use iio_pollfunc_store_time X-Git-Tag: rel_imx_5.10.35_2.0.0-somdevices.0~5215^2~80^2~21 X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=0a3f50e4d698e3d46ce10171dcd076c927bb60a8;p=linux.git iio:bmi160: use iio_pollfunc_store_time Currently, we snap the timestamp after reading from the buffer and processing the event. When the IIO poll function is triggered by an interrupt, we can get a slightly more accurate timestamp by snapping it prior to reading the data, since the data was already generated prior to entering the trigger handler. This is not going to make a huge difference, but we might as well improve slightly. Do this by using iio_pollfunc_store_time as other drivers do.
