commit c42f8218610aa09d7d3795e5810387673c1f84b6 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 device creation will result in undefined
behaviour when configfs is built as a module since the configfs group for
the device not properly initialized.
Similar to commit b2f0c09664b7 ("iio: sw-trigger: Fix config group
initialization").

iio: Add support for creating IIO devices via configfs2016-05-04T10:43:54+00:00Daniel Balutadaniel.baluta@intel.com2016-04-25T13:15:51+00:00urn:sha1:0f3a8c3f34f728e7c96651bb7271e1c388c9aac2
This is similar with support for creating triggers via configfs.
Devices will be hosted under:
* /config/iio/devices
We allow users to register "device types" under:
* /config/iio/devices/<device_types>/
