From 293487c8ecc1103f4625cea5e90e1ba0cc89660f Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Tue, 10 Feb 2015 18:33:51 +0200 Subject: iio: Export userspace IIO headers After UAPI header file split [1] all user-kernel interfaces were placed under include/uapi/. This patch moves IIO user specific API from: * include/linux/iio/events.h => include/uapi/linux/iio/events.h * include/linux/types.h => include/uapi/linux/types.h Now there is no need for nasty tricks to compile userspace programs (e.g iio_event_monitor). Just installing the kernel headers with make headers_install command does the job.
