[SCSI] lpfc: Move a dereference below a NULL test
In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: James Smart <James.Smart@Emulex.Com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
