arch/powerpc/sysdev/ehv_pic.c: add missing kfree
At this point, ehv_pic has been allocated but not stored anywhere, so it should be freed before leaving the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
