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").
Fixes: 0f3a8c3f34f7 ("iio: Add support for creating IIO devices via configfs")
