[PATCH] ASoC: rsnd: remove unneeded of_node_put()

[PATCH] ASoC: amd: yc: Fix non-functional mic on Lenovo 82QF and 82UG
by August Wikerfors 12 Sep '23

12 Sep '23

Like the Lenovo 82TL and 82V2, the Lenovo 82QF (Yoga 7 14ARB7) and 82UG (Legion S7 16ARHA7) both need a quirk entry for the internal microphone to function. Commit c008323fe361 ("ASoC: amd: yc: Fix a non-functional mic on Lenovo 82SJ") restricted the quirk that previously matched "82" to "82V2", breaking microphone functionality on these devices. Fix this by adding specific quirks for these models, as was done for the Lenovo 82TL.

[PATCH v4 00/11] sound: Use -EPROBE_DEFER instead of i915 module loading.
by Maarten Lankhorst 12 Sep '23

12 Sep '23

Explicitly loading i915 becomes a problem when upstreaming the new intel driver for Tiger Lake and higher graphics (xe). By loading i915, it doesn't wait for driver load of xe, and will fail completely before it loads. -EPROBE_DEFER has to be returned before any device is created in probe(), otherwise the removal of the device will cause EPROBE_DEFER to try again in an infinite loop. The conversion is done in gradual steps. First I add an argument to snd_hdac_i915_init to allow for -EPROBE_DEFER so I can convert each driver separately. Then I convert each driver to move snd_hdac_i915_init out of the workqueue. Finally I drop the ability to choose modprobe behavior after the last user is converted. Compared to previous version, I picked up Pierre's changes to add a probe_no_wq, added remove_no_wq myself and then fixed the SOF changes to use it.

[PATCH] ALSA: core: Use dev_name of card_dev as debugfs directory name
by Peter Ujfalusi 12 Sep '23

12 Sep '23

There is no need to use temporary string for the debugfs directory name as we can use the device name of the card. This change will also fixes the following compiler warning/error (W=1): sound/core/init.c: In function ‘snd_card_init’: sound/core/init.c:367:28: error: ‘%d’ directive writing between 1 and 10 bytes into a region of size 4 [-Werror=format-overflow=] 367 | sprintf(name, "card%d", idx); | ^~ sound/core/init.c:367:23: note: directive argument in the range [0, 2147483646] 367 | sprintf(name, "card%d", idx); | ^~~~~~~~ sound/core/init.c:367:9: note: ‘sprintf’ output between 6 and 15 bytes into a destination of size 8 367 | sprintf(name, "card%d", idx); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors The idx is guarantied to be less than SNDRV_CARDS (max 256 or 8) by the code in snd_card_init(), however the compiler does not see that. The warnings got brought to light by a recent patch upstream: commit 6d4ab2e97dcf ("extrawarn: enable format and stringop overflow warnings in W=1") Suggested-by: Arnd Bergmann <arnd(a)arndb.de> Suggested-by: Takashi Iwai <tiwai(a)suse.de> Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> --- sound/core/init.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/sound/core/init.c b/sound/core/init.c index d61bde1225f2..22c0d217b860 100644 --- a/sound/core/init.c +++ b/sound/core/init.c @@ -278,9 +278,6 @@ static int snd_card_init(struct snd_card *card, struct device *parent, size_t extra_size) { int err; -#ifdef CONFIG_SND_DEBUG - char name[8]; -#endif if (extra_size > 0) card->private_data = (char *)card + sizeof(struct snd_card); @@ -364,8 +361,8 @@ static int snd_card_init(struct snd_card *card, struct device *parent, } #ifdef CONFIG_SND_DEBUG - sprintf(name, "card%d", idx); - card->debugfs_root = debugfs_create_dir(name, sound_debugfs_root); + card->debugfs_root = debugfs_create_dir(dev_name(&card->card_dev), + sound_debugfs_root); #endif return 0; -- 2.42.0
