From: Julia Lawall <julia@xxxxxxx> In each case, the NULL test has been performed already. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression *x; expression e; identifier l; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != goto l; when != x = e when != &x *x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/media/dvb/frontends/stv0900_core.c | 5 ----- drivers/media/video/cpia.c | 3 --- 2 files changed, 8 deletions(-) diff --git a/drivers/media/dvb/frontends/stv0900_core.c b/drivers/media/dvb/frontends/stv0900_core.c index 74791d5..9052a9b 100644 --- a/drivers/media/dvb/frontends/stv0900_core.c +++ b/drivers/media/dvb/frontends/stv0900_core.c @@ -1410,11 +1410,6 @@ static enum fe_stv0900_error stv0900_init_internal(struct dvb_frontend *fe, return error; } - if (state->internal == NULL) { - error = STV0900_INVALID_HANDLE; - return error; - } - intp = state->internal; intp->demod_mode = p_init->demod_mode; diff --git a/drivers/media/video/cpia.c b/drivers/media/video/cpia.c index 551ddf2..933ae4c 100644 --- a/drivers/media/video/cpia.c +++ b/drivers/media/video/cpia.c @@ -3737,9 +3737,6 @@ static int cpia_mmap(struct file *file, struct vm_area_struct *vma) if (size > FRAME_NUM*CPIA_MAX_FRAME_SIZE) return -EINVAL; - if (!cam || !cam->ops) - return -ENODEV; - /* make this _really_ smp-safe */ if (mutex_lock_interruptible(&cam->busy_lock)) return -EINTR; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
