[PATCH] powerpc/eeh: Delete an error message for a failed memory allocation in two functions

From: Markus Elfring <redacted>
Date: Fri, 4 Aug 2017 16:37:56 +0200

Omit an extra message for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.

Applied to powerpc next, thanks.

Thanks that you picked another update suggestion up.

* It might matter to mention that only one patch hunk was accepted in this case.

* Can it be that the adjusted commit subject does contain a typo at the moment?
  Would the wording “powerpc/eeh: Delete a message for an "out of memory error"
  (at init time)” be more appropriate there?

Regards,
Markus
