[PATCH 0/4] Input: use parallel port device model

[Sudip Mukherjee]

Hi,
This series will convert the other remaining drivers to use parallel
port device model. Changes are similar to the changes done in db9.c

regards
sudip

Sudip Mukherjee (4):
  Input: gamecon - use parallel port device model
  Input: turbografx - use parallel port device model
  Input: serio - use parallel port device model
  Input: walkera0701 - use parallel port device model
