FWIW I am seeing the same crash/regression, however, the bisect is pointing to commit b9f2e25c599bbbf0646957e07ebb72b942c286cc ("ASoC: soc-core: use soc_find_component() at snd_soc_find_dai()") and reverting this commit fixes the problem for me. Dmitry, are you sure it is this commit? They do have a similar name. Cheers Jon -- nvpublic
