[ Upstream commit 5967577231f9b19acd5a59485e9075964065bbe3 ]
Misuse of CONFIG_* in UAPI headers should result in an error. These config options can be set in userspace by the user application which includes these headers to control the APIs and structures being used in a kernel which supports multiple targets.
