The struct s626_enc_info is used in this driver to defined the callbacks and other data needed to handle each encoder "channel". These "channel" numbers are the same as the comedi_subdevice channels.
The channels specific stuff can easily be handled run-time by just using the subdevice channel number. The first 17 patches in this series remove members from the struct. The final patch removes the struct completely.
