From 76c317d6e5cb7f58541879006d39774596962715 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 19 Jul 2009 17:26:13 +0200 Subject: HID: Move dereferences below a NULL test If the NULL test is necessary, then the dereferences should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ type T; expression E,E1; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E=E1 when != i if (E == NULL||...)
