UBIFS: use an IS_ERR test rather than a NULL test
In case of error, the function kthread_create returns an ERR pointer, but never returns a NULL pointer. So a NULL test that comes before an IS_ERR test should be deleted. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = kthread_create(...) ... when != x = E * if (x == NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
