RDMA/ucma: Test ucma_alloc_multicast() return against NULL, not with IS_ERR()
In case of error, the function ucma_alloc_multicast() returns a NULL pointer, but never returns an ERR pointer. So after a call to this function, an IS_ERR test should be replaced by a NULL test. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match bad_is_err_test@ expression x, E; @@ x = ucma_alloc_multicast(...) ... when != x = E IS_ERR(x) // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Roland Dreier <rolandd@cisco.com>
