Thanks for the patch Naresh, it looks correct but I've not seen this
build error myself. Could you please let me know what you built to get
this and if you have any suggestion on what caused it? (So we can add a
Fixes: tag etc)

Regards,
Bjorn

Thanks for the review.
This was an arm64 modules build failure on linux -next 20200616 tag.
This fix has already been taken care of by
Herbert Xu <herbert@gondor.apana.org.au> and got merged.
