[SCSI] libfc: Correct use of ! and &
!ep->esb_stat is either 1 or 0, and the rightmost bit of ESB_ST_COMPLETE is always 0, making the result of !ep->esb_stat & ESB_ST_COMPLETE always 0. Thus parentheses around the argument to ! seem needed. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E; constant C; @@ ( !E & !C | - !E & C + !(E & C) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
