[PATCH 2/6] macio: Make remove callback of macio driver void returned
by Dawei Li 05 Dec '22

05 Dec '22

Commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for macio bus based drivers.

[PATCH 3/6] apr: make remove callback of apr driver void returned
by Dawei Li 05 Dec '22

05 Dec '22

Since commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for apr bus based drivers.

[PATCH] ASoC: soc-compress: Reposition and add pcm_mutex
by 강신형 05 Dec '22

05 Dec '22

>From 3f8fd1efedd77331d948b16a8e44ffa6cf0e811f Mon Sep 17 00:00:00 2001 From: "s47.kang" <s47.kang(a)samsung.com> Date: Fri, 2 Dec 2022 18:32:35 +0900 Subject: [PATCH] [COMMON] ASoC: soc-compress.c: Reposition and add pcm_mutex. 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 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.

[PATCH 0/3] ALSA: Fix XRUN handling of USB-audio implicit fb
by Takashi Iwai 05 Dec '22

05 Dec '22

Hi, this is a patch set to cover a corner-case bug that happens with the USB-audio implicit feedback mode. When XRUN happens in the implicit fb full-duplex streams, the driver may get EPIPE error at prepare but re-issuing fails again. The essential fix is the 3rd patch but the former two are covering other corner cases I spotted (only theoretical).

[PATCH v8 0/3] ASoC: SOF: Fix deadlock when shutdown a frozen userspace
by Ricardo Ribalda 05 Dec '22

05 Dec '22

Since: 83bfc7e793b5 ("ASoC: SOF: core: unregister clients and machine drivers in .shutdown") we wait for all the workloads to be completed during shutdown. This was done to avoid a stall once the device is started again. Unfortunately this has the side effect of stalling kexec(), if the userspace is frozen. Let's handle that case.
