ASoC: codecs: aw88261: only check PLL and clock state at power-up

2026-09-11T09:49:40+00:00

[ Upstream commit 06b6f1245567a4be862c3e1cc74577922ceb05fb ] The SYSST check performed during device start requires SWS (amplifier switching, bit 8) and BSTS (boost finished, bit 9) on top of PLL lock and clock stability. Those bits cannot be asserted at this point in the sequence: the check runs after amppd release but before the hmute/ULS-hmute release, and the amplifier neither switches nor finishes ramping its boost converter while it is still muted. With the Fairphone (Gen. 6) firmware profile, aw88261_dev_start() therefore always fails with check sysst fail, reg_val=0x0011, check:0x311 and playback aborts, even though the amplifier is fine and PLL lock and stable clocks are present. Check only PLL lock and clock stability, for which a definition already exists; this still re-validates the clocks after amppd release (aw88261_dev_check_syspll() checked them before it). This matches the vendor aw882xx driver, which only validates PLL lock and clock stability at this stage, and the in-tree aw88399 driver, which skips the SWS check whenever the amplifier may legitimately not be switching (AW88399_BIT_SYSST_NOSWS_CHECK).

ASoC: codecs: aw88261: reduce log spam

2026-09-11T09:49:40+00:00

[ Upstream commit d90c361af215a9fa2a986d9f47d554d0cf3401dd ] This driver would create a wall of logspam during initialization due to e.g. the PLL not being ready while waiting for it to stabilize. Change intermediate dev_err() calls to dev_dbg() to reduce the noise. While here, log the detected chip ID when that check fails.

ASoC: samsung: aries_audio_probe: double of_node_put due to direct assignment without of_node_get

2026-09-11T09:49:18+00:00

commit fb5d1b1c5f8a920ee697545fa6dee16825085717 upstream. In aries_audio_probe(), aries_dai[0].platforms->of_node is assigned the same pointer as aries_dai[0].cpus->of_node (from of_parse_phandle) without calling of_node_get(). When the sound card is deregistered, the ASoC framework calls of_node_put() on both cpus->of_node and platforms->of_node, causing a double put on the same node and a refcount underflow. Add of_node_get(aries_dai[0].cpus->of_node) before the assignment.

ASoC: loongson: Fix error handling in ACPI property parsing

2026-09-11T09:49:18+00:00

commit 0eb0e3c623ac1da8b85d518043fef7660af7805d upstream. In loongson_card_parse_acpi(), the return value of device_property_read_string() for the `codec-dai-name` property was ignored. If the property is missing or invalid, an uninitialized pointer would be used later, potentially leading to undefined behavior. Fix this by checking the return value and propagating the error appropriately.

AsoC: intel: sst: fix PCI device reference leak on probe failure

2026-09-11T09:49:18+00:00

commit 016f29997ebd29d6ab59c8162ce0e7f73bd1e517 upstream. intel_sst_probe() takes a reference to the PCI device with pci_dev_get(). If sst_platform_get_resources() fails afterwards, the probe error path cleans up the driver context but does not drop the PCI device reference. Add a pci_dev_put() error path for failures after pci_dev_get().

ASoC: hdac_hda: Fix hlink refcount leak on component registration failure

2026-09-11T09:49:18+00:00

commit 6ad4892c4f5cb437a928a02f5b7d37d496aa9268 upstream. hdac_hda_dev_probe() gets the HDA link with snd_hdac_ext_bus_link_get() before registering the ASoC component. If component registration fails, the function returns without dropping the link reference. Always call snd_hdac_ext_bus_link_put() after the registration attempt so the reference taken during probe is balanced on both success and failure.

ASoC: cs35l34: drain threaded IRQ before runtime suspend

2026-09-11T09:49:18+00:00

commit 4105a4c0678b2808fc8046b60321b4f1cc7dae75 upstream. cs35l34_runtime_suspend() currently switches the codec into regcache_cache_only(true), asserts reset low, and powers the device off without first quiescing the threaded IRQ registered by devm_request_threaded_irq(). That leaves a window where cs35l34_irq_thread() can still run after suspend has removed live hardware access. A running system can reach this during runtime PM while the driver still has critical fault IRQs unmasked. If the threaded handler runs in that window, it reads volatile INT_STATUS_1..4 after cache_only has been enabled, ignores the regmap_read() failures, and can still execute the PROT_RELEASE_CTL release sequence or the BST fault power-down writes. Use disable_irq() before entering cache_only/reset-low/power-off so any in-flight threaded handler is drained and no new IRQ thread can run while the device is suspended. Re-enable the IRQ only after runtime_resume() has restored live register access with regcache_sync(). Since probe only logs request_threaded_irq() failures and keeps going, track whether the IRQ was actually installed before disabling or re-enabling it.

That leaves a window where cs35l33_irq_thread() can still run after suspend has closed off live register access. A running system can reach this during runtime PM while the driver still has critical fault IRQs unmasked.

Use disable_irq() before entering cache_only/power-off so any in-flight threaded handler is drained and no new IRQ thread can run during the suspended state. Re-enable the IRQ only after runtime_resume() has restored live register access with regcache_sync().
