SA1111: Eliminate use after free
__sa1111_remove always frees its argument, so the subsequent reference to
sachip->saved_state represents a use after free. __sa1111_remove does not
appear to use the saved_state field, so the patch simply frees it first.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E,E2;
@@
__sa1111_remove(E)
...
(
E = E2
|
* E
)
// </smpl>
