   4 Subject: iio: accel: kionix-kx022a: Get the timestamp from the driver's private data in the trigger_handler
   5

   8 commit 03fada47311a3e668f73efc9278c4a559e64ee85 upstream.
   9
  10 The trigger_handler gets called from the IRQ thread handler using
  11 iio_trigger_poll_chained() which will only call the bottom half of the
  12 pollfunc and therefore pf->timestamp will not get set.
  13
  14 Use instead the timestamp from the driver's private data which is always
  15 set in the IRQ handler.
