4.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Lars-Peter Clausen <[email protected]> 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.
