Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. The original commit was incorrect, the error needs to be propagated back to the caller AND if the second group call fails, the first needs to be removed. There are much better ways to solve this, the driver should NOT be calling sysfs_create_group() on its own as it is racing userspace and loosing.
