[GIT PULL] TDA998x I2C driver development updates

[Russell King]

David,

Please incorporate the latest TDA998x I2C driver development updates,
which can be found at:

  git://git.armlinux.org.uk/~rmk/linux-arm.git drm-tda998x-devel

with SHA1 9b2502b6ebc632ff49743b3639ea12d4f08808a5.

These updates:
* improve the robustness of the driver wrt races
* improve the compliance for sending infoframes and audio
* re-organise the function order in the driver to group like functions
  together.  (This unfortunately causes a conflict with the change in
  drm-misc, but it should be trivial to solve, although it looks more
  scarey than it really is - sfr has already sent two reports about
  this, one earlier today.)
* simplify tda998x_audio_get_eld and DPMS handling
* power down sections of the chip that we never use
* add some initial preparation for supporting the CEC driver

This will update the following files:
