[PATCH] iio: Use type header from kernel tree

From: Laura Abbott
Date: Fri Sep 09 2016 - 11:25:27 EST



The iio tools have been updated as new event types have been added to
the kernel. The tools currently use the standard system headers which
means that the system may not have the newest defintitions. This leads
to build failures when building newer tools on older hosts:

gcc -Wall -g -D_GNU_SOURCE -c -o iio_event_monitor.o
iio_event_monitor.c
iio_event_monitor.c:59:3: error: âIIO_UVINDEXâ undeclared here (not in a
function)
[IIO_UVINDEX] = "uvindex",
^~~~~~~~~~~
iio_event_monitor.c:59:3: error: array index in initializer not of
integer type
iio_event_monitor.c:59:3: note: (near initialization for
âiio_chan_type_name_specâ)
iio_event_monitor.c:97:3: error: âIIO_MOD_LIGHT_UVâ undeclared here (not
in a function)
[IIO_MOD_LIGHT_UV] = "uv",
^~~~~~~~~~~~~~~~
iio_event_monitor.c:97:3: error: array index in initializer not of
integer type
iio_event_monitor.c:97:3: note: (near initialization for
âiio_modifier_namesâ)
<builtin>: recipe for target 'iio_event_monitor.o' failed

Switch to using the header from the kernel tree to ensure the newest
defintions are always picked up.
