  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.

• cf5842de7   Add scripts/coccinelle/alloc/kzalloc-simple.cocci ... Browse Code »

  This semantic patch replaces a pair of calls to kmalloc and memset
  by a single call to kzalloc.

  It only looks for simple cases to avoid false positives.
