ALSA: usb-audio: qcom: Check offload mapping failures

2026-05-15T06:51:46+00:00

uaudio_transfer_buffer_setup() calls dma_get_sgtable() and then passes the sg_table to uaudio_iommu_map_xfer_buf() without checking whether sg table construction succeeded. If dma_get_sgtable() fails, the sg_table contents are not valid. uaudio_iommu_map_pa() also ignores iommu_map() failures for the event and transfer rings and still returns the allocated IOVA to the QMI response. That can expose an unmapped IOVA to the audio DSP. For transfer rings, the failed mapping also leaves the IOVA allocator state marked in use. Check both operations. Free the coherent transfer buffer when sg table construction fails, free the sg table when transfer-buffer IOMMU mapping fails, and release the transfer-ring IOVA if iommu_map() fails. Also return the existing event-ring IOVA when the event ring is already mapped, matching the pre-split helper behavior.

Merge tag 'asoc-v7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v7.1 There's one new core feature here but mostly this has been a fairly quiet release, we've got a few new drivers and one core feature that's likely to be relatively rarely used but the bulk of the work this time around has been on quality. - Support for bus keepers, this will be used by the Apple device support. - Enhancements to the SDCA support, incuding retaskable jacks. - Unwinding of the pcm_new()/pcm_free() cleanups from Morimoto-san. - Test improvements for the Cirrus Logic drivers. - Large sets of fixes for the NXP, nVidia and Qualcomm drivers. - Support for AMD RPL DMICs, Cirrus Logic CS42L43 and CS47L47, nVidia machines with CPCAP and WM8962.

Pull USB/Thunderbolt fixes from Greg KH: "Here are a bunch of USB and Thunderbolt fixes (most all are USB) for 7.0-rc7. More than I normally like this late in the release cycle, partly due to my recent travels, and partly due to people banging away on the USB gadget interfaces and apis more than normal (big shoutout to Android for getting the vendors to actually work upstream on this, that's a huge win overall for everyone here) Included in here are: - Small thunderbolt fix - new USB serial driver ids added - typec driver fixes - gadget driver fixes for some disconnect issues - other usb gadget driver fixes for reported problems with binding and unbinding devices as happens when a gadget device connects / disconnects from a system it is plugged into (or it switches device mode at a user's request, these things are complex little beasts...) - usb offload fixes (where USB audio tunnels through the controller while the main CPU is asleep) for when EMP spikes hit the system causing disconnects to happen (as often happens with static electricity in the winter months). This has been much reported by at least one vendor, and resolves the issues they have been seeing with this codepath. Can't wait for the "formal methods are the answer!" people to try to model that one properly... - Other small usb driver fixes for issues reported. All of these have been in linux-next this week, and before, with no reported issues, and I've personally been stressing these harder than normal on my systems here with no problems" * tag 'usb-7.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (39 commits) usb: gadget: f_hid: move list and spinlock inits from bind to alloc usb: host: xhci-sideband: delegate offload_usage tracking to class drivers usb: core: use dedicated spinlock for offload state usb: cdns3: gadget: fix state inconsistency on gadget init failure usb: dwc3: imx8mp: fix memory leak on probe failure path usb: gadget: f_uac1_legacy: validate control request size usb: ulpi: fix double free in ulpi_register_interface() error path usb: misc: usbio: Fix URB memory leak on submit failure USB: core: add NO_LPM quirk for Razer Kiyo Pro webcam usb: cdns3: gadget: fix NULL pointer dereference in ep_queue usb: core: phy: avoid double use of 'usb3-phy' USB: serial: option: add MeiG Smart SRM825WN usb: gadget: f_rndis: Fix net_device lifecycle with device_move usb: gadget: f_subset: Fix net_device lifecycle with device_move usb: gadget: f_eem: Fix net_device lifecycle with device_move usb: gadget: f_ecm: Fix net_device lifecycle with device_move usb: gadget: u_ncm: Add kernel-doc comments for struct f_ncm_opts usb: gadget: f_rndis: Protect RNDIS options with mutex usb: gadget: f_subset: Fix unbalanced refcnt in geth_free dt-bindings: connector: add pd-disable dependency ...

usb: host: xhci-sideband: delegate offload_usage tracking to class drivers

2026-04-02T07:43:30+00:00

Remove usb_offload_get() and usb_offload_put() from the xHCI sideband interrupter creation and removal paths. The responsibility of manipulating offload_usage now lies entirely with the USB class drivers. They have the precise context of when an offload data stream actually starts and stops, ensuring a much more accurate representation of offload activity for power management.

ASoC: partial match the sdca codec name

Merge series from Bard Liao : Currently, we set a predefined codec component name in a DAI link. But the codec name may contain an index which is not fixed. This series suggest using partial match the codec name to fix the issue.
