This exported element needs to be accesible to all drivers using configfs within IIO. Previously it was in the sw_trig.h file which only convered one such usecase. This also fixes a sparse warning as it is now in a header that makes sense to include from industrialio-configfs.c Signed-off-by: Jonathan Cameron < jic23@kernel.org>
