Subject: [PATCH net-next 1/9] net: Remove martian_source_keep_err goto label
Date: Wed, 23 Sep 2015 08:15:14 -0700	[thread overview]
Message-ID: <1443021322-48621-2-git-send-email-dsa@cumulusnetworks.com> (raw)
In-Reply-To: <1443021322-48621-1-git-send-email-dsa@cumulusnetworks.com>

err is initialized to -EINVAL when it is declared. It is not reset until
fib_lookup which is well after the 3 users of the martian_source jump. So
resetting err to -EINVAL at martian_source label is not needed.

Removing that line obviates the need for the martian_source_keep_err label
so delete it.
