Subject: iio: sw-device: Fix config group initialization
From: Lars-Peter Clausen <[email protected]>
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").
