Steven,
Take Joe Perches' patch, put a proper change log on it and test it.
Hopefully Joe will agree to a SoB and we will do that instead of the
Markus Elfring thing.
Thanks,
David

Omit an extra message for a memory allocation failure in this function.
This issue was detected by using the Coccinelle software.

You really should reverse the test here and
unindent the first block.
Again: Don't be mindless.
Take the time to improve the code.
