Smatch reports a warning: drivers/media/usb/tm6000/tm6000-video.c:646 tm6000_prepare_isoc() error: we previously assumed 'dev->urb_buffer' could be null (see line 624) This is not really a problem, but it actually shows that the check if urb_buffer is NULL is being done twice: at the if and at tm6000_alloc_urb_buffers(). We don't need to do it twice. So, remove the extra check. The code become cleaner, and, as a collateral effect, smatch becomes happy. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
