[PATCH 1/2] ASoC: max98090: Reject invalid values in custom control put()
by Mark Brown 25 Apr '22

25 Apr '22

The max98090 driver has a custom put function for some controls which can only be updated in certain circumstances which makes no effort to validate that input is suitable for the control, allowing out of spec values to be written to the hardware and presented to userspace. Fix this by returning an error when invalid values are written.

[RFC PATCH 0/5] Apple Macs machine-level ASoC driver
by Martin Povišer 25 Apr '22

25 Apr '22

Hi, I put together a machine-level ASoC driver for recent Apple Macs (the ones with ARM64 SoCs) and want to gauge opinions. Commit 1 is the binding. It is some subset of simple-audio-card with the extra distinction of allowing multiple CPU/CODEC DAIs per a DAI link. I want to draw special attention to the issue of describing speaker topologies. The way it now works is that the driver expects the speakers to be declared in a fixed order in the sound-dai= list. This populates a topology the driver expects on a particular machine model. Mark (in CC) has made the suggestion of keeping the topology descriptions with the codec nodes themselves in some generic manner, akin to how sound-name-prefix= already helps identify codecs to the user. Commit 2 adds a new ASoC card method (filter_controls) to let the card prevent some codec kcontrols from being visible to userspace. For example the TAS2770 speaker amp driver would be happy to expose TDM slot selection and ISENSE/VSENSE enables which is ridiculous. I am all ears on how to make the patch acceptable to upstream. Commit 3 makes ASoC tolerate N-to-M DAI links, not sure what the right (simple) approach should be there. Commit 4 adds some utility function and commit 5 is the driver itself. Let me know what you think.

[PATCH 0/2] ASoC: Add macros for signed TLV controls with callbacks
by Richard Fitzgerald 25 Apr '22

25 Apr '22

This adds SOC_DOUBLE_R_S_EXT_TLV and SOC_SINGLE_S_EXT_TLV macros for signed TLV controls that need custom get/put callbacks. These will be needed by future Cirrus codec drivers, but are not particularly exotic so could be useful for others.

[PATCH 0/3] firewire: fixes for kernel v4.9 or later
by Takashi Sakamoto 25 Apr '22

25 Apr '22

Hi, This patchset respins patches posted before to fix some bugs for Linux FireWire subsystem. I expect them to be sent to Linus via pull request by maintainer of Linux sound subsystem since the path appears to be available after a short conversation with the maintainer. This patchset is expected to be applied to 'for-linus' branch for v5.18 kernel, and to stable kernels based on v4.9 or later. This patchset includes below patches: * [PATCH V2] drivers/firewire: use struct_size over open coded arithmetic * https://lore.kernel.org/lkml/20220210060805.1608198-1-chi.minghao@zte.com.c… * [PATCH] firewire: core: extend card->lock in fw_core_handle_bus_reset * https://lore.kernel.org/lkml/20220303183038.54126-1-dossche.niels@gmail.com/ * [PATCH] firewire: remove check of list iterator against head past the loop body * https://lore.kernel.org/lkml/20220331223601.902329-1-jakobkoschel@gmail.com/ Chengfeng Ye (1): firewire: fix potential uaf in outbound_phy_packet_callback() Jakob Koschel (1): firewire: remove check of list iterator against head past the loop body Niels Dossche (1): firewire: core: extend card->lock in fw_core_handle_bus_reset drivers/firewire/core-card.c | 3 +++ drivers/firewire/core-cdev.c | 4 +++- drivers/firewire/core-topology.c | 9 +++------ drivers/firewire/core-transaction.c | 30 +++++++++++++++-------------- drivers/firewire/sbp2.c | 13 +++++++------ 5 files changed, 32 insertions(+), 27 deletions(-) -- 2.34.1

[PATCH] ALSA: fireworks: fix wrong return count shorter than expected by 4 bytes
by Takashi Sakamoto 25 Apr '22

25 Apr '22

ALSA fireworks driver has a bug in its initial state to return count shorter than expected by 4 bytes to userspace applications when handling response frame for Echo Audio Fireworks transaction. It's due to missing addition of the size for the type of event in ALSA firewire stack.
