Subject: staging: comedi: adv_pci1760: Do not return EINVAL for CMDF_ROUND_DOWN.
X-Git-Tag: v4.8-rc5~8^2~9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c71f20ee76342376e3c4c67cdbe7421d8c4e886e;p=karo-tx-linux.git

staging: comedi: adv_pci1760: Do not return EINVAL for CMDF_ROUND_DOWN.

The CMDF_ROUND_DOWN case falls through and so always returns -EINVAL.

Fixes: 14b93bb6bbf0 ("staging: comedi: adv_pci_dio: separate out PCI-1760 support")
