6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: João Paulo Gonçalves joao.goncalves@toradex.com
commit 74cb21576ea5247efbbb7d92f71cafee12159cd9 upstream.
The condition for checking if triggers belong to the same IIO device to set attached_own_device is currently inverted, causing iio_trigger_using_own() to return an incorrect value. Fix it by testing for the correct return value of iio_validate_own_trigger().
