[alsa-devel] [patch] ALSA: emu10k1: shift wrapping bug in snd_emu10k1_ptr_read()
by Dan Carpenter 24 Nov '16

24 Nov '16

Static analysis says "size" is a number 0-63. So we really want to be doing the shift as a u64 and not a int type. Presumably "size" is never actually more than 31 otherwise the shift wrap would have been detected in testing. The "mask" is a u32 so we only care about the bottom 32 bits which also implies that "size" is less than 32. This code pre-dates git. I haven't tested this change, it's to fix a static analysis warning. I can't think that shift wrapping is the correct behavior so presumably this change is harmless but it definitely changes how the code works when size is larger than 32.

[alsa-devel] [PATCH 1/2] ALSA: hda - ignore the assoc and seq when comparing pin configurations
by Hui Wang 24 Nov '16

24 Nov '16

More and more pin configurations have been adding to the pin quirk table, lots of them are only different from assoc and seq, but they all apply to the same QUIRK_FIXUP, if we don't compare assoc and seq when matching pin configurations, it will greatly reduce the pin quirk table size. We have tested this change on a couple of Dell laptops, it worked well. Cc: <stable(a)vger.kernel.org> Signed-off-by: Hui Wang <hui.wang(a)canonical.com> --- No hurry to cleanup the existing pin quirk table, if this patch run well for a period of time, then I will do the cleanup little by little.

[alsa-devel] [RFC v2 0/3] ALSA controls management using index/device/sub-devices fields
by Arnaud Pouliquen 24 Nov '16

24 Nov '16

V2: Aim of this version is to continue discussion on DAI PCM control focused on ASoC drivers. In this V2 implementation in Soc-core is simplified to limit impact on existing code. Proposal is to add field in DAI driver struct to declare PCM controls that need to be linked to PCM character device on DAI link probing. Update of the RFC V1 based on discussions: - [RFC 4/4] iecset: allow to select control with device and sub-device numbers no more part of the RFC V2, will be discussed in a separate thread - [RFC 2/4] ALSA: control: increment index field for duplicated control. no more part of the RFC V2, no more need as RFC subject is PCM controls - [RFC V2 1/3] ASoC: core: allow DAI PCM controls bound to PCM device Patch reworked from V1 to simplify implementation - Binding is not done for Dai links tagged with no_pcm (DPCM). - no more possibility to add the controls after the DAI link probing. - [RFC V2 2/3] ASoC: sti: bind PCM controls to PCM device. - [RFC V2 3/3] ASoC: hdmi-codec: Example of PCM control bound to PCM device for multi Example of implementation in STI DAI driver and HDMI-codec drivers V1: http://www.spinics.net/lists/alsa-devel/msg56479.html 1) Alsa-utils patch - iecset: allow to select control with device and sub-device numbers This patch allows to access to 2 iec controls differentiated by device/sub-devices numbers => For me, this patch is mandatory to be able to address the ASoC IEC controls, in case of no fix is implemented to allows index field update in ASoC. 2) Alsa driver patches - ASoC: core: allow PCM control binding to PCM device Add relationship between DAIs PCM controls and PCM device. - ALSA: control: increment index field for duplicated control.

[alsa-devel] [PATCH] dbri: Fix compiler warning
by Tushar Dave 23 Nov '16

23 Nov '16

dbri uses 'u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit DMA and therefore dma_addr_t became of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. sound/sparc/dbri.c: In function ‘snd_dbri_create’: sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’ This patch resolves above compiler warning.

[alsa-devel] [PATCH] ASoC: ab8500: Remove explicit initialization of driver callbacks to NULL
by Lars-Peter Clausen 23 Nov '16

23 Nov '16

Fields of structs with global storage are implicitly initialized to 0/NULL, there is usually no need to do this explicitly. Removing the initialization of the legacy suspend/resume callback fields also gets the driver ready for the day when they are eventually removed.

[alsa-devel] [PATCH 1/2] ASoC: uda1380: Remove unused DAI ID defines
by Lars-Peter Clausen 23 Nov '16

23 Nov '16

The DAI ID defines are back from the time when DAIs were referenced by a numerical ID. These days a string is used for matching instead and the defines are unused. The last user of these defines was removed in commit f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). So remove the defines as well.
