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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
