changeset 5eeb3014827f added a fixup at the error check
code. However, it introduced a new error:
drivers/media/usb/cx231xx/cx231xx-cards.c:1586 cx231xx_usb_probe()
error: we previously assumed 'dev' could be null (see line 1430)
This happens when dev = kmalloc() fails. So, instead of relying
on it to succeed, just change the parameter of clear_bit() from
'dev->devno' to 'nr'.
