Three patches to remove two empty branches and a little code simplification. v2->v3: 1. Drop patch #3. 2. Factor out sas_check_edge_expander_topo(). 3. Factor out sas_check_fanout_expander_topo(). v1->v2: 1. Add blank line after declaration in sas_eeds_valid(). 2. Drop the inner-most and outter-most parenthesis in sas_eeds_valid(). 3. Break the long line in the declaration of sas_check_phy_topology(). 4. Move "else if" to the same line after "}".
