Commit 5d5b4128c4ca ("devlink: introduce flash update overwrite mask") added a usage of _BITUL to the UAPI <linux/devlink.h> header, but failed to include the header file where it was defined. It happens that this does not break any existing kernel include chains because it gets included through other sources. However, when including the UAPI headers in a userspace application (such as devlink in iproute2), _BITUL is not defined.
