The patch itself looks reasonable. The caller only cares about is the
return code negative or not. So returning -ENOMEM or -1 makes no
difference.
Please take a look at:

You need to specify a tree you want this merged via.
If you consider this a fix, you need to add a Fixes: tag. However, i
don't see this patch meeting stable requirements.
If this is just normal development, net-next is closed at the moment
for the merge window. Please repost in two weeks time.
