[alsa-devel] [PATCH 1/2] ASoC: fix pcm-creation regression
by Johan Hovold 18 Jul '17

18 Jul '17

This reverts commit 99b04f4c4051 ("ASoC: add Component level pcm_new/pcm_free"), which started calling the pcm_new callback for every component in a *card* when creating a new pcm, something which does not seem to make any sense. This specifically led to memory leaks in systems with more than one platform component and where DMA memory is allocated in the platform-driver callback. For example, when both mcasp devices are being used on an am335x board, DMA memory would be allocated twice for every DAI link during probe. When CONFIG_SND_VERBOSE_PROCFS was set this fortunately also led to warnings such as: WARNING: CPU: 0 PID: 565 at ../fs/proc/generic.c:346 proc_register+0x110/0x154 proc_dir_entry 'sub0/prealloc' already registered Since there seems to be no users of the new component callbacks, and the current implementation introduced a regression, let's revert the offending commit for now.

For hdspm, we have a local buffer of the same size as its substring. In this case, making the buffer a little longer is safe as the functions that take it as an argument all use length checking and the strings we pass into it are actually short enough.

[alsa-devel] Reset to clean state after snd_ctl_add_integer_elem_set ?
by Fulup Ar Foll 18 Jul '17

18 Jul '17

I'm using snd_ctl_add_boolean_elem_set and snd_ctl_add_integer_elem_set to create some user kernel controls. While the operation work find I did not find any simple command to erase all those controls. Even "/usr/sbin/alsactl --init" does not remove those added controls. The only way I find is to prevent /usr/sbin/alsactlto happen during reboot to really reset the ALSA driver to an initial state, which is really not pratical when developing/debugging. Question: is there a simple method to return to a clean and fresh state after snd_ctl_add_xxxx without rebooting the machine ? Thank you Fulup

[alsa-devel] [PATCH v1] ALSA: fm801: Initialize chip after IRQ handler is registered
by Andy Shevchenko 18 Jul '17

18 Jul '17

The commit b56fa687e02b ("ALSA: fm801: detect FM-only card earlier") rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to be called before we register interrupt handler and set PCI bus mastering. Somehow it prevents FM801-AU to work properly. Thus, partially revert initialization order changed by commit mentioned above.

[alsa-devel] [PATCH] ASoC: rsnd: remove unnecessary static in rsnd_ssiu_probe()

Remove unnecessary static on local variable ops. Such variable is initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the code size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see the difference in the code size.

[alsa-devel] Applied "ASoC: fsi: constify dev_pm_ops structure" to the asoc tree

17 Jul '17

The patch ASoC: fsi: constify dev_pm_ops structure has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 4b2983da22d30c53d778b2e5035dc347dc4b0037 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R.
