4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Phil Turnbull <phil.turnbull@xxxxxxxxxx>
commit c71f20ee76342376e3c4c67cdbe7421d8c4e886e upstream.
The CMDF_ROUND_DOWN case falls through and so always returns -EINVAL.
Fixes: 14b93bb6bbf0 ("staging: comedi: adv_pci_dio: separate out PCI-1760 support")
