Masami Hiramatsu (Google) 6338bb05c1 error-injection: remove EI_ETYPE_NONE
Patch series "error-injection: Clarify the requirements of error
injectable functions".

Patches for clarifying the requirement of error injectable functions and
to remove the confusing EI_ETYPE_NONE.


This patch (of 2):

Since the EI_ETYPE_NONE is confusing type, replace it with appropriate
errno.  The EI_ETYPE_NONE has been introduced for a dummy (error) value,
but it can mislead people that they can use ALLOW_ERROR_INJECTION(func,
NONE).  So remove it from the EI_ETYPE and use appropriate errno instead.
