From: Julia Lawall <julia@xxxxxxx> It seems impossible for ov to be NULL at this point. The semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression E, E1; identifier f; statement S1,S3; iterator iter; @@ if ((E == NULL && ...) || ...) { ... when != false ((E == NULL && ...) || ...) when != true ((E != NULL && ...) || ...) when != iter(E,...) S1 when != E = E1 ( sizeof(E->f) | * E->f ) ... when any return ...; } else S3 // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/media/video/ov511.c | 5 ----- 1 files changed, 0 insertions(+), 5 deletions(-) diff --git a/drivers/media/video/ov511.c b/drivers/media/video/ov511.c index e0bce8d..dd1b1ac 100644 --- a/drivers/media/video/ov511.c +++ b/drivers/media/video/ov511.c @@ -5916,11 +5916,6 @@ ov51x_disconnect(struct usb_interface *intf) mutex_lock(&ov->lock); usb_set_intfdata (intf, NULL); - if (!ov) { - mutex_unlock(&ov->lock); - return; - } - /* Free device number */ ov511_devused &= ~(1 << ov->nr); -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
