IB/usnic: delete unneeded IS_ERR test
kzalloc doesn't return ERR_PTR, so there is no need to test for it. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; @@ * x = kzalloc(...) ... when != x = e * IS_ERR_OR_NULL(x) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Dave Goodell <dgoodell@cisco.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
