[GIT PULL]

[Haavard Skinnemoen <hskinnemoen@atmel.com>]

Linus,

Please pull from

  ssh://master.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git for-linus

to receive the following updates. This is mostly about connecting a few
loose ends that came in through other trees, that is make sure that the
new drivers can actually be used on avr32.

Alejandro Martinez Ruiz (1):
      [AVR32] ARRAY_SIZE() cleanup

Haavard Skinnemoen (3):
      [AVR32] Fix a couple of sparse warnings
      [AVR32] Implement more at32_add_device_foo() functions
      [AVR32] Implement at32_add_device_cf()

Hans-Christian Egtvedt (1):
      [AVR32] Wire up AT73C213 sound driver on ATSTK1000 board

Kristoffer Nyborg Gregertsen (1):
      [AVR32] Platform code for pata_at32
