In this code, it is possible to tell statically whether usblp will be NULL in the error handling code. Oliver Neukum suggested to make a goto to the final return rather than return directly. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ identifier f,err,l,l1; type T; expression x,E; statement S; @@ x = NULL ... when != goto l1; * x = f(...) ... when != x err = E; goto l; ... * if (x != NULL) S return err; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
