Subject: [PATCH 2/2] drivers/scsi/sun3x_esp.c: Convert && to ||

From: Julia Lawall <julia@...u.dk>

The pattern !E && !E->fld is nonsensical.  The patch below updates this
according to the assumption that && should be ||.  But perhaps another
solution was intended.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@disable and_comm@
expression E;
identifier fld;
@@

- !E && !E->fld
+ !E || !E->fld
// </smpl>

Signed-off-by: Julia Lawall <julia@...u.dk>
