So, the HDMI log spam I reported against 3.2-rc1 in this thread:

is actually slightly worse now (see below), despite the fact that it was
eliminated by the patch I tested. Looking at the git log, I see a patch
similar to the one sent to me was merged as part of a larger series:

3a9627f4fbb0 ("drm/i915: dont trigger hotplug events on unchanged ELD")

and indeed, by building the tree after checking out that specific commit
there is no spam. However, the _very next commit_:

2deed761188d ("drm/i915: HDMI hot remove notification to audio driver")

reintroduces the log spam every mode change, with two additional lines
printed each time (the lines prefixed with an asterisk are new):

* HDMI hot plug event: Codec=3 Pin=3 Presence_Detect=0 ELD_Valid=1
* HDMI status: Codec=3 Pin=3 Presence_Detect=0 ELD_Valid=0
HDMI hot plug event: Codec=3 Pin=3 Presence_Detect=1 ELD_Valid=1
HDMI status: Codec=3 Pin=3 Presence_Detect=1 ELD_Valid=1
HDMI: detected monitor W2253 at connection type HDMI
HDMI: available speakers: FL/FR
HDMI: supports coding type LPCM: channels = 2, rates = 32000 44100 48000, bits = 16 20 24
