[media] drivers/media/video/davinci/vpbe_display.c: eliminate a null pointer dereference
In the original code, probe_out could be reached when res was null and then when the irq had not yet been requested. In those cases, the call to free_irq is not needed, so move probe_out down and introduce a new label for the case where calling free_irq is useful. The semantic match that finds this problem is as follows: // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...) S1 else S2 when != E = E1 *E->f ... when any return ...; } else S3 // </smpl> Signed-off-by:Julia Lawall <julia@diku.dk> Signed-off-by:
