fs/dlm: Drop unnecessary null test
hlist_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,E,E1,E2; statement S,S1,S2; @@ I(x,...) { <... - (x != NULL) && E ...> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David Teigland <teigland@redhat.com>
