From: Alan Cox Date: Mon, 17 Sep 2012 10:54:15 +0000 (+0100) Subject: wireless: remove unreachable code X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=f3baed51f44dd6b6c7076d2de24d8aed291d8130;p=~shefty%2Frdma-dev.git wireless: remove unreachable code The only case where intersected_rd can become non NULL is within an if. All paths from that if return, so the end chunk has therefore squawked its last and is no more.
