This does not match your subject... and having subject twice is also confusing. Please fix your mailer.
Additionally, this is like third patch, right? So please mark it as v3 (git format-patch helps in this).
If panic_on_warn is set and compress stream(DPCM) is started, then kernel panic will occurs because card->pcm_mutex isn't held appropriately in
So the problem is panic_on_warn or wrong synchronization? It's the second, so skip unrelated information and instead describe the real problem, e.g. what exactly lockdep reported.
soc_compr_set_params_fe, soc_compr_open_fe and soc_compr_free_fe. So, I reposition and add pcm_mutex to resolve lockdep error.
