Fix those warnings: drivers/media/pci/mantis/mantis_cards.c:73 mantis_irq_handler() error: we previously assumed 'mantis' could be null (see line 72) drivers/media/pci/mantis/hopper_cards.c:64 hopper_irq_handler() error: we previously assumed 'mantis' could be null (see line 63) Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/pci/mantis/hopper_cards.c | 4 +--- drivers/media/pci/mantis/mantis_cards.c | 4 +--- 2 files changed, 2 insertions(+), 6 deletions(-) diff --git a/drivers/media/pci/mantis/hopper_cards.c b/drivers/media/pci/mantis/hopper_cards.c index 67aebe759232..c0bd5d7e148b 100644 --- a/drivers/media/pci/mantis/hopper_cards.c +++ b/drivers/media/pci/mantis/hopper_cards.c @@ -60,10 +60,8 @@ static irqreturn_t hopper_irq_handler(int irq, void *dev_id) struct mantis_ca *ca; mantis = (struct mantis_pci *) dev_id; - if (unlikely(!mantis)) { - dprintk(MANTIS_ERROR, 1, "Mantis == NULL"); + if (unlikely(!mantis)) return IRQ_NONE; - } ca = mantis->mantis_ca; stat = mmread(MANTIS_INT_STAT); diff --git a/drivers/media/pci/mantis/mantis_cards.c b/drivers/media/pci/mantis/mantis_cards.c index deadd0b92233..906e4500d87d 100644 --- a/drivers/media/pci/mantis/mantis_cards.c +++ b/drivers/media/pci/mantis/mantis_cards.c @@ -69,10 +69,8 @@ static irqreturn_t mantis_irq_handler(int irq, void *dev_id) struct mantis_ca *ca; mantis = (struct mantis_pci *) dev_id; - if (unlikely(mantis == NULL)) { - dprintk(MANTIS_ERROR, 1, "Mantis == NULL"); + if (unlikely(!mantis)) return IRQ_NONE; - } ca = mantis->mantis_ca; stat = mmread(MANTIS_INT_STAT);
