Subject: net/passt: Remove unused "err" from passt_vhost_user_event() (CID 1612375)
X-Git-Tag: v10.1.0-rc0~8^2~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ed74e3c005f236acbf7d85d396a653bfb004a17;p=thirdparty%2Fqemu.git

net/passt: Remove unused "err" from passt_vhost_user_event() (CID 1612375)

The "err" variable was declared but never used within the
passt_vhost_user_event() function. This resulted in a dead code
warning (CID 1612375) from Coverity.

Remove the unused variable and the associated error block
to resolve the issue.
