[PATCH 00/14] More HDMI fixes V2

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Following the comments I received and the discussions I had on IRC with Chris
and Daniel, here is the updated version. Even patch 0001 had changes, so I had
to do small adjustments on basically every single patch of the series so they
apply again.

Here is a list of changes:

0001: Add 'static' keywords (suggested by Chris)
0002: Small code change to be more defensive
0004: Add WARN to prevent future mistakes (suggested by Daniel)
0007: Small code change to be more defensive

New patches:
0012: drm/i915: clarify confusion between HDMI and SDVO registers
0013: drm/i915: add some barriers when changing DIPs
0014: drm/i915: make sure HDMI port is disabled inside set_infoframes

Patch 12 is my attempt to fix confusing names and prevent regressions like the
one that happened recently. Patch 13 was suggested by Chris and patch 14 was
suggested by Daniel.

So now the code seems pretty defensive :)

After this series is applied, I think we should go through bugzilla and start
suggesting people to test their HDMI bugs against the new tree.

Cheers,
Paulo
