IB/ehca: Drop unnecessary NULL test
list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ iterator I; expression x; statement S,S1,S2; @@ I(x,...) { <... - if (x == NULL && ...) S ...> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Alexander Schmidt <alexs@linux.vnet.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
