[alsa-devel] [PATCH] ASoC: q6routing: initialize data correctly
by Srinivas Kandagatla 03 Sep '18

03 Sep '18

Some of the router data fields are left as default zeros which are valid dai ids, so initialize these to invalid value of -1. Without intializing these correctly get_session_from_id() can return incorrect session resulting in not closing the opened copp and messing up with the copp ref count.

[alsa-devel] [PATCH v2 0/2] Add support for MikroElektronika PROTO codec
by Codrin Ciubotariu 03 Sep '18

03 Sep '18

This patchset is based on Florian's initial PROTO driver: https://lkml.org/lkml/2013/5/22/342 My changes made the driver more generic, so that we could connect other I2S CPU DAIs, by using device-tree. Tested with sama5d2 I2S driver. Changes in v2: - removed unnecessary code that added constraints for the fixed SYSLK; - fixed errors reported by kbuild; - adjusted "mikroe" in vendor prefixes; - updated description in Kconfig; Codrin Ciubotariu (2): ASoC: Add driver for PROTO Audio CODEC (with a WM8731) ASoC: mikroe-proto: dt-bindings: add DT bindings for PROTO board .../bindings/sound/mikroe,mikroe-proto.txt | 23 +++ .../devicetree/bindings/vendor-prefixes.txt | 1 + sound/soc/atmel/Kconfig | 11 ++ sound/soc/atmel/Makefile | 2 + sound/soc/atmel/mikroe-proto.c | 165 ++++++++++++++++++ 5 files changed, 202 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/mikroe,mikroe-proto.txt create mode 100644 sound/soc/atmel/mikroe-proto.c -- 2.17.1

[alsa-devel] ASoC: pxa: remove pxa2xx-pcm driver, which caused regression
by petrcvekcz＠gmail.com 02 Sep '18

02 Sep '18

From: Petr Cvek <petrcvekcz(a)gmail.com> The switch of PXA to dmaengine caused a regression for devices which are using SSP/I2S and probably AC97. The problem is in multiple allocation of DMA by function pxa2xx_soc_pcm_new() called by pxa-pcm-audio and (SSP/I2S/AC97). The regression was found on HTC Magician and after playback kernel generates an oops: WARNING: CPU: 0 PID: 892 at drivers/dma/dmaengine.c:788 dma_release_channel+0x44/0xa0 chan reference count 0 != 1 Modules linked in: ... snd_soc_magician snd_soc_uda1380 snd_soc_pxa2xx_i2s spi_pxa2xx_platform snd_soc_pxa2xx snd_soc_pxa_ssp snd_pxa2xx_lib snd_pcm_dmaengine i2c_pxa snd_soc_core snd_pcm snd_timer i2c_core snd ssp soundcore [last unloaded: pwm_bl] CPU: 0 PID: 892 Comm: aplay Tainted: G C 4.18.0-rc6-next-20180726-magician+ #16 Hardware name: HTC Magician [<c0107d90>] (unwind_backtrace) from [<c010594c>] (show_stack+0x10/0x14) [<c010594c>] (show_stack) from [<c0111680>] (__warn+0xd4/0xec) [<c0111680>] (__warn) from [<c01112d0>] (warn_slowpath_fmt+0x44/0x6c) [<c01112d0>] (warn_slowpath_fmt) from [<c034908c>] (dma_release_channel+0x44/0xa0) [<c034908c>] (dma_release_channel) from [<bf330528>] (snd_dmaengine_pcm_close_release_chan+0x44/0xb1c [snd_pcm_dmaengine]) [<bf330528>] (snd_dmaengine_pcm_close_release_chan [snd_pcm_dmaengine]) from [<bf26c29c>] (soc_pcm_components_close+0x8c/0xac [snd_soc_core]) [<bf26c29c>] (soc_pcm_components_close [snd_soc_core]) from [<bf26c3a0>] (soc_pcm_close+0xe4/0xd44 [snd_soc_core]) [<bf26c3a0>] (soc_pcm_close [snd_soc_core]) from [<bf167254>] (snd_pcm_release_substream+0x88/0x108 [snd_pcm]) [<bf167254>] (snd_pcm_release_substream [snd_pcm]) from [<bf167330>] (snd_pcm_release+0x5c/0xd2c [snd_pcm]) [<bf167330>] (snd_pcm_release [snd_pcm]) from [<c01c39e4>] (__fput+0xdc/0x1e8) [<c01c39e4>] (__fput) from [<c0129e7c>] (task_work_run+0xc4/0xd4) [<c0129e7c>] (task_work_run) from [<c01053ac>] (do_work_pending+0xc0/0xc8) [<c01053ac>] (do_work_pending) from [<c0101068>] (slow_work_pending+0xc/0x20) Exception stack(0xc2fdffb0 to 0xc2fdfff8) ffa0: 00000000 0154d1a0 01542a3c 00000000 ffc0: 0154d150 00000000 0009283c 00000006 000003f0 0154d4c8 00000000 0154d4c8 ffe0: b6ee7d70 bef13960 b6e547b8 b6cfe018 60000010 00000004 Removing bindings for snd_soc_magician fixes the problem (tested). Other machines should have the same problem if they use at least one of pxa-ssp-dai or pxa2xx-i2s. Considering pxa2xx-ac97 uses the function pxa2xx_soc_pcm_new() too it should produce the same problem (untested). After removal from I2S/SSP/AC97 machines there seems to be no user of pxa2xx-pcm, so remove the driver completely, change platform device in arch/arm/mach-pxa/devices.c to snd-soc-dummy and an example in the documentation.

[alsa-devel] [PATCH] ALSA: control: Make sure that id->index does not overflow in function snd_ctl_replace
by Xiao Yang 01 Sep '18

01 Sep '18

From: Young_X <YangX92(a)hotmail.com> The ALSA control code expects that the range of assigned indices to a control is continuous and does not overflow. Currently there are no checks to enforce this. If a control with a overflowing index range is created that control becomes effectively inaccessible and unremovable since snd_ctl_find_id() will not be able to find it. This patch adds a check that makes sure that controls with a overflowing index range can not be created.
