[PATCH] staging: comedi: refactor dyna_pci10xx driver to remove forward declarations

From: H Hartley Sweeten
Date: Fri May 04 2012 - 19:50:31 EST


Move the struct comedi_driver and associated variables to the
end of the source. This is more typical of how other drivers are
written and removes the need for the forward declarations.
