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/). The result has been modified to move the initialization of usb down closer to where it is used. // <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> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
Todo: - checkpatch.pl cleanups - sparse cleanups - lots of little modules, should be merged together and added to the build. - testing? - handle churn in v4l layer. Please send patchs to Greg Kroah-Hartman <greg@kroah.com> and Cc: Ross Cohen <rcohen@snurgle.org> as well.
