[alsa-devel] [PATCH 1/4] sound/soc/kirkwood/kirkwood-i2s.c: add missing kfree

[Julia Lawall]

From: Julia Lawall <julia at diku.dk>

Adjust the goto to jump to the error handling code that includes kfree.

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

// <smpl>
@@
identifier x;
expression E1!=0,E2,E3,E4;
statement S;
iterator I;
@@

(
if (...) { ... when != kfree(x)
               when != x = E3
               when != E3 = x
*  return ...;
 }
... when != x = E2
    when != I(...,x,...) S
if (...) { ... when != x = E4
 kfree(x); ... return ...; }
)
// </smpl>
