Subject: [PATCH 3.16 301/346] IB/mlx4: Fix code indentation in QP1 MAD flow

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jack Morgenstein <jackm@....mellanox.co.il>

commit baa0be7026e2f7d1d40bfd45909044169e9e3c68 upstream.

The indentation in the QP1 GRH flow in procedure build_mlx_header is
really confusing. Fix it, in preparation for a commit which touches
this code.
