staging: comedi: adv_pci_dio: Advantech PCI-1739U support
This patch is ported over by me (Ian Abbott) from the out-of-tree Comedi git repository at "git://comedi.org/git/comedi/comedi.git". The original patch is by Nicholas Nell. ----- Advantech PCI-1739U support Hello, I've added a bit of simple configuration to adv_pci_dio.c in order to make the PCI-1739U work with the adv_pci_dio driver. I have tested inputs only so far but they seem to work. A git style patch is attached. Thanks, -- Nicholas Nell Professional Research Assistant University of Colorado ----- Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Cc: Nico Nell <nicholas.nell@colorado.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
