[PATCH 5.1 31/85] iio: adc: ti-ads8688: fix timestamp is not updated in buffer

[Greg Kroah-Hartman]

From: Sean Nyekjaer <s...@geanix.com>

commit e6d12298310fa1dc11f1d747e05b168016057fdd upstream.

When using the hrtimer iio trigger timestamp isn't updated.
If we use iio_get_time_ns it is updated correctly.
