+ * Documentation/fault-injection/fault-injection.rst for details. The macro
+ * ALLOW_ERROR_INJECTION() is used to conditionally skip function execution
+ * at runtime and use a provided return value. The first requirement for
+ * error injectable functions is proper handling of the error code by the
+ * caller for recovery, which is always the case here. The second
+ * requirement is that no state is changed before the first error return.
+ * It is not strictly fullfilled for all initialization functions using the
+ * ALLOW_ERROR_INJECTION() macro but this is acceptable because for those
+ * error cases at probe time, the error code is simply propagated up by the
+ * caller. Therefore there is no consequence on those specific callers when
+ * function error injection skips the whole function.
