[PATCH 0/4] CBUS patches

[Felipe Balbi]

Hi Tony,

removed a few unneeded includes and moved platform_device
registration to board file.

ps: as usual, compile tested only :-p No working n810 available

Felipe Balbi (4):
  cbus: remove unneded includes
  cbus: retu: move platform_device to board file
  cbus: tahvo: move platform_device to board file
  cbus: tahvo-usb: move platform_device to board file

[PATCH 1/4] cbus: remove unneded includes

[Felipe Balbi]

we don't use anything from those headers,
thus removing them.

Jarkko Nikula reminded me about 770. It also has cbus so it's now
missing the platform_devices hehe. Sorry about that. Forget about these
patches.
