patch "iio: sw-device: Fix config group initialization" added to staging-linus

This is a note to let you know that I've just added the patch titled

iio: sw-device: Fix config group initialization

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: iio: sw-device: Fix config group initialization

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").
