4.7-stable review patch.  If anyone has any objections, please let me know.


From: Lars-Peter Clausen <l...@metafoo.de>

commit b2f0c09664b72b2f8c581383a9337ac3092e42c8 upstream.

Use the IS_ENABLED() helper macro to ensure that the configfs group is
initialized either when configfs is built-in or when configfs is built as a
module. Otherwise software trigger creation will result in undefined
behaviour when configfs is built as a mdoule since the configfs group for
the trigger is not properly initialized.

Fixes: b662f809d410 ("iio: core: Introduce IIO software triggers")
