Message-ID: <201205151342.04700.hartleys@visionengravers.com>

Subject: [PATCH] staging: comedi: refactor adl_pci9118 driver and use module_comedi_pci_driver
Move the module_init/module_exit routines and the associated
struct comedi_drive and struct pci_driver to the end of the
source. This is more typical of how other drivers are written
and removes the need for the forward declarations.
Convert the driver to use the module_comedi_pci_driver() macro
which makes the code smaller and a bit simpler.
While moving the struct boardtype, convert it to C99 initializers
to improve code readability. This results is a slight increase in
the total lines of code.
