From: Colin Ian King <colin.king@canonical.com>
The variable x is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.
Addresses-Coverity: ("Unused value")

Hi Dan,
I'd post a revert, but I don't seem to see an upstream commit for this
this to revert against. What's the revert policy in these cases? Or can
the patch be just ignored by the maintainers so it's not applied?
Colin

It has not been applied, and will be ignored, in part thanks to the
report.
However I think Dan's report is misleading in that it looks like it's
about a commit while I think it should emphasize that it's a pre-merge
report on the patch on the mailing list.

To be honest, these are auto-generated by the kbuild bot and I was a bit
confused myself.
