[PATCH] ASoC: qdsp6: fix a use after free bug in open()
by Dan Carpenter 05 Jan '22

05 Jan '22

This code frees "graph" and then dereferences to save the error code. Save the error code first and then use gotos to unwind the allocation.

No need. Here just update the ak4497_fs_mul table, before it is used the codec type is checked. Best regards Wang Shengjiu

[PATCH v2 1/3] ASoC: cs4265: Fix part number ID error message
by Fabio Estevam 04 Jan '22

04 Jan '22

From: Fabio Estevam <festevam(a)denx.de> The Chip ID - Register 01h contains the following description as per the CS4265 datasheet: "Bits 7 through 4 are the part number ID, which is 1101b (0Dh)" The current error message is incorrect as it prints CS4265_CHIP_ID, which is the register number, instead of printing the expected part number ID value. To make it clearer, also do a shift by 4, so that the error message would become: [ 4.218083] cs4265 1-004f: CS4265 Part Number ID: 0x0 Expected: 0xd Signed-off-by: Fabio Estevam <festevam(a)denx.de> Acked-by: Charles Keepax <ckeepax(a)opensource.cirrus.com> --- Changes since v1: - None sound/soc/codecs/cs4265.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/soc/codecs/cs4265.c b/sound/soc/codecs/cs4265.c index cffd6111afac..b89002189a2b 100644 --- a/sound/soc/codecs/cs4265.c +++ b/sound/soc/codecs/cs4265.c @@ -611,8 +611,8 @@ static int cs4265_i2c_probe(struct i2c_client *i2c_client, if (devid != CS4265_CHIP_ID_VAL) { ret = -ENODEV; dev_err(&i2c_client->dev, - "CS4265 Device ID (%X).

hda/cs8904: Fix jack detection after resume
by Christian A. Ehrhardt 04 Jan '22

04 Jan '22

Hi, while debugging something different, I found the following jack detection related bug in the cs8904 driver on my DELL Inspirion 3501: - Plug in a headset, play some sound to make sure that the headset is detected. - Stop the sound, wait for the codec to go into suspend (30s should be plenty enough time) - Unplug the headset while the codec is in suspend. - Try to play sound on the internal speakers. Notice that the the driver still thinks the headset is connected. As a result there is no sound on the internal speakers. AFAICS the bug was introduced by the following commit: | commit 424e531b47f83da87490464c5bf633dfb624fe6a | Author: Stefan Binding <sbinding(a)opensource.cirrus.com> | Date: Fri Aug 27 12:02:51 2021 +0100 | | ALSA: hda/cs8409: Ensure Type Detection is only run on startup when | necessary The bug is with the hp_jack_in and mic_jack_in flags that are used to determine if jack detection should be run etc. These flags are cleared in the suspend path. This prevents a status change from being detected after resume as hp_jack_in is cleared by suspend and there is no jack due to the unplug of the headset. This status change was never reported to the HDA core, though. On suspend this is not done, only hd_jack_in is cleared and on resume the driver thinks that there is no change the needs reporting. Proposed fix below, please consider inclusion. regards Christian >From 1dcf34c1d1c6c4852a86ec3ae189afa5d90ea09c Mon Sep 17 00:00:00 2001 From: "Christian A.

Unbinding and rebinding the driver using sysfs fixes it, thats the current workaround I have been using. Thanks and happy holidays, Rouven Czerwinski

[PATCH] mips: bcm63xx: add support for clk_set_parent()
by Randy Dunlap 03 Jan '22

03 Jan '22

The MIPS BMC63XX subarch does not provide/support clk_set_parent(). This causes build errors in a few drivers, so add a simple implementation of that function so that callers of it will build without errors. Fixes these build errors: ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined! ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!
