Add scripts/coccinelle/deref_null.cocci

Add scripts/coccinelle/err_cast.cocci

2010-06-11T22:00:29Z

Add a Coccinelle file to use the ERR_CAST function Before the release 2.6.25, one had to use ERR_PTR(PTR_ERR(...)) to convert the pointer type of an error. Since then, the function ERR_CAST has been available for that purpose. Signed-off-by: Nicolas Palix Signed-off-by: Julia Lawall Signed-off-by: Michal Marek

2010-06-11T22:00:29Z

Add scripts/coccinelle/alloc/kzalloc-simple.cocci

2010-06-11T22:00:29Z
