[ Upstream commit3b75dd76e6] init_annotated_branch_stats() and all_annotated_branch_stats() check the return value of register_stat_tracer() with "if (!ret)", but register_stat_tracer() returns 0 on success and a negative errno on failure. The inverted check causes the warning to be printed on every successful registration, e.g.: Warning: could not register annotated branches stats while leaving real failures silent. The initcall also returned a hard-coded 1 instead of the actual error. Invert the check and propagate ret so that the warning fires on real errors and the initcall reports the correct status.
