And from crash_console_flush.
We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

-registers x0 through x5 to do its work. The return value is 0 on successful
-completion; otherwise the return value is -1.
