Julia Lawall 0d0659c78d arch/sparc/kernel: Eliminate what looks like a NULL pointer dereference 
At the point of the test, action cannot be NULL, as it has been dereferenced
in the code just above.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@

if ((E == NULL && ...) || ...)
{
  ... when != if (...) S1 else S2
      when != E = E1
* E->f
  ... when any
}
else S3
// </smpl>
