Subject: [PATCH 4.19 26/73] iio: adc: ti-ads8688: fix timestamp is not updated in buffer

From: Sean Nyekjaer <sean@...nix.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.

Fixes: 2a86487786b5c ("iio: adc: ti-ads8688: add trigger and buffer support")
