This sounds like the most likely explanation.  There's not that many
commits, would it be possible for you to try bisecting them (or just
reverting them one at a time)?  The most salient ones should be:

356bccbea17988bd32a016ada867dd6a53ba2796 ASoC: omap-abe-twl6040: Introduce driver data for runtime parameters
7d09f9e98956b29755f20d830252dec9300e7044 ASoC: omap-abe-twl6040: Move Digital Mic widget into dapm table
c2f98956e3635a897737cc08a60539752aa00dd7 ASoC: omap-abe-twl6040: Keep only one snd_soc_dai_link structure

though it looks like a bisect of sound/soc/omap should be about as fast.
Like I say if we're talking late July or August there's a very good
chance that 3.5 will be broken so we should at least revert but it'd be
a shame to loose the HDMI stuff, I'd really expect that to be unrelated.
