Add "Pro Audio" profile for UMC204HD
by GitHub pull_request - opened 14 May '22

14 May '22

alsa-project/alsa-ucm-conf pull request #153 was opened from brndd: Follow-up to #128 I figured that some users might prefer to keep the channel mapping untouched from what the card defaults to when unconfigured. Providing an alternative profile like this (implementation adapted from #145) for these users seems like a good idea. I believe PipeWire autogenerates profiles like these for unconfigured devices, so that's where the "Pro Audio" nomenclature comes from. Likely a good idea to match that since PipeWire is increasingly the default on most distributions.

Re: [PATCH 19/32] afs: Use mem_to_flex_dup() with struct afs_acl

That's really quite unpleasant syntax. Is it not possible to have mem_to_flex_dup() and friends work without that?

Either do: acl = mem_to_flex_dup(buffer, size, GFP_KERNEL); if (!acl) or: acl = mem_to_flex_dup(buffer, size, GFP_KERNEL); if (IS_ERR(acl)) Please especially don't make it that an apparent 'true' return indicates an error. If you absolutely must return the acl pointer through the argument list (presumably because it's actually a macro), make it return false on failure: if (!mem_to_flex_dup(&acl, buffer, size, GFP_KERNEL)) or return and explicitly check for an error code: if (mem_to_flex_dup(&acl, buffer, size, GFP_KERNEL) < 0) or: ret = mem_to_flex_dup(&acl, buffer, size, GFP_KERNEL); if (ret < 0) (or use != 0 rather than < 0) David

I would say that it's actually less clear. In a bunch of places, you've done something like: - e = kmalloc(...); - if (!e) + if (__mem_to_flex_dup(&e, ...)) The problem is that, to me at least, it looks like: - e = kmalloc(...); - if (kmalloc failed) + if (__mem_to_flex_dup(&e, ...) succeeded) David

[PATCH] ALSA: hda/intel: Add quirk for TongFang devices with pop noise
by Werner Sembach 12 May '22

12 May '22

When audio stops playing and sometimes when it starts playing, there is an audible "pop" noise when using headphones on most Tongfang GMxMxxx, GKxNxxx, GMxZxxx, GMxTxxx, and GMxAxxx devices. Disabling power saving for the Realtek codec fixes this noise. Presumably it is triggered on some power event in the audio circuit.

[PATCH] ASoC: samsung: Fix refcount leak in aries_audio_probe

12 May '22

of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. If extcon_find_edev_by_node() fails, it doesn't call of_node_put() Calling of_node_put() after extcon_find_edev_by_node() to fix this.
