media: mantis: fix two smatch errors
Drop two dprintk's that relied on a non-NULL mantis pointer when it was in fact a NULL pointer. 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 <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
