Xy220 device bug ?

[cjm@mail.ast.cam.ac.uk (Chris Mayer)]

We have been trying to use the Xy220 via a mbbo and found that we could not
drive the outputs that we wanted. Looking at the device layer code it seems
there is a missing shift operator in the init_record procedure i.e.

  pmbbo->mask = pmbbo->shft

should read

  pmbbo->mask <<= pmbbo->shft

has anyone else come across this problem and / or is this the correct way to 
fix it ? We are running r3.11.4 epics but looking in the beta release of r3.12
that we have appears to show the same problem.
