[PATCH 4.7 106/141] staging: comedi: adv_pci1760: Do not return EINVAL for CMDF_ROUND_DOWN.

[Greg Kroah-Hartman]

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")
