[PATCH AUTOSEL 6.18-6.17] ALSA: hda/realtek: Add support for ASUS UM3406GA

by Sasha Levin

From: Stefan Binding <sbinding(a)opensource.cirrus.com> [ Upstream commit 826c0b1ed09e5335abcae07292440ce72346e578 ] Laptops use 2 CS35L41 Amps with HDA, using External boost, with I2C Signed-off-by: Stefan Binding <sbinding(a)opensource.cirrus.com> Link: https://patch.msgid.link/20251205150614.49590-3-sbinding@opensource.cirrus.… Signed-off-by: Takashi Iwai <tiwai(a)suse.de> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: ## Commit Analysis: ALSA: hda/realtek: Add support for ASUS UM3406GA ### 1. COMMIT MESSAGE ANALYSIS The commit message is straightforward: it adds support for a specific ASUS laptop model (UM3406GA) that uses 2 CS35L41 amplifiers connected via I2C with external boost. The message describes the hardware configuration, which is standard for such device ID additions. No Fixes: or Cc: stable tags are present, but as noted, this is expected for commits requiring manual review. ### 2. CODE CHANGE ANALYSIS The entire change is a single line addition: ```c SND_PCI_QUIRK(0x1043, 0x1584, "ASUS UM3406GA ", ALC287_FIXUP_CS35L41_I2C_2), ``` This adds: - Vendor ID: 0x1043 (ASUS) - Device/Subsystem ID: 0x1584 (ASUS UM3406GA) - Fixup: `ALC287_FIXUP_CS35L41_I2C_2` (an **existing** fixup already used by many other ASUS models) Looking at the surrounding code, multiple other ASUS laptops use the same fixup: - ASUS PM3406CKA (0x1454) - ASUS G513PI/PU/PV (0x14e3) - ASUS G733PY/PZ/PZV/PYV (0x1503) - ASUS GV302XA/XJ/XQ/XU/XV/XI (0x1533) - ASUS UM3402YAR (0x1683) ### 3. CLASSIFICATION This is a **NEW DEVICE ID** addition - explicitly listed as an exception that IS appropriate for stable backporting. The driver infrastructure and fixup code already exist; this merely adds an ID to enable the existing fix for new hardware. ### 4. SCOPE AND RISK ASSESSMENT - **Lines changed**: 1 line - **Files touched**: 1 file - **Complexity**: Zero - table entry addition only - **Risk**: Extremely low - this cannot affect any other hardware - **No new code paths**: Uses pre-existing `ALC287_FIXUP_CS35L41_I2C_2` fixup ### 5. USER IMPACT - **Who is affected**: Owners of ASUS UM3406GA laptops - **Problem without fix**: Audio (specifically the CS35L41 amplifiers) won't function properly - **Severity**: Non-working audio is a significant user-facing issue for laptop users ### 6. STABILITY INDICATORS - Signed-off by Takashi Iwai (ALSA maintainer at SUSE) - Standard quirk addition pattern used extensively throughout this file - Follows exact same format as dozens of other ASUS quirk entries ### 7. DEPENDENCY CHECK - The fixup `ALC287_FIXUP_CS35L41_I2C_2` has been in the kernel for some time, supporting multiple other ASUS models - No other commits are required for this to work - This should apply cleanly to stable trees that have the CS35L41 support infrastructure ### CONCLUSION This commit is a textbook example of what should be backported to stable trees: 1. **Falls under explicit exception**: Adding device IDs to existing drivers is explicitly allowed 2. **Minimal change**: Single line, single table entry 3. **Zero regression risk**: Cannot affect any hardware except the targeted laptop 4. **Uses existing infrastructure**: The fixup is already well-tested on similar ASUS models 5. **Fixes real user problem**: Enables audio on a production laptop 6. **Obviously correct**: Identical pattern to surrounding entries The risk-benefit analysis strongly favors backporting: virtually zero risk with clear user benefit (working audio on a specific laptop model). **YES** sound/hda/codecs/realtek/alc269.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/hda/codecs/realtek/alc269.c b/sound/hda/codecs/realtek/alc269.c index b45fcc9a3785e..008bf9d5148e1 100644 --- a/sound/hda/codecs/realtek/alc269.c +++ b/sound/hda/codecs/realtek/alc269.c @@ -6752,6 +6752,7 @@ static const struct hda_quirk alc269_fixup_tbl[] = { SND_PCI_QUIRK(0x1043, 0x1517, "Asus Zenbook UX31A", ALC269VB_FIXUP_ASUS_ZENBOOK_UX31A), SND_PCI_QUIRK(0x1043, 0x1533, "ASUS GV302XA/XJ/XQ/XU/XV/XI", ALC287_FIXUP_CS35L41_I2C_2), SND_PCI_QUIRK(0x1043, 0x1573, "ASUS GZ301VV/VQ/VU/VJ/VA/VC/VE/VVC/VQC/VUC/VJC/VEC/VCC", ALC285_FIXUP_ASUS_HEADSET_MIC), + SND_PCI_QUIRK(0x1043, 0x1584, "ASUS UM3406GA ", ALC287_FIXUP_CS35L41_I2C_2), SND_PCI_QUIRK(0x1043, 0x1652, "ASUS ROG Zephyrus Do 15 SE", ALC289_FIXUP_ASUS_ZEPHYRUS_DUAL_SPK), SND_PCI_QUIRK(0x1043, 0x1662, "ASUS GV301QH", ALC294_FIXUP_ASUS_DUAL_SPK), SND_PCI_QUIRK(0x1043, 0x1663, "ASUS GU603ZI/ZJ/ZQ/ZU/ZV", ALC285_FIXUP_ASUS_HEADSET_MIC), -- 2.51.0

This can cause the following lockdep splat with shared GPIOs enabled on boards which have multiple devices using the same GPIO: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:591 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 12, name: kworker/u16:0 preempt_count: 1, expected: 0 RCU nest depth: 0, expected: 0 6 locks held by kworker/u16:0/12: #0: ffff0001f0018d48 ((wq_completion)events_unbound#2){+.+.}-{0:0}, at: process_one_work+0x18c/0x604 #1: ffff8000842dbdf0 (deferred_probe_work){+.+.}-{0:0}, at: process_one_work+0x1b4/0x604 #2: ffff0001f18498f8 (&dev->mutex){....}-{4:4}, at: __device_attach+0x38/0x1b0 #3: ffff0001f75f1e90 (&gdev->srcu){.+.?}-{0:0}, at: gpiod_direction_output_raw_commit+0x0/0x360 #4: ffff0001f46e3db8 (&shared_desc->spinlock){....}-{3:3}, at: gpio_shared_proxy_direction_output+0xd0/0x144 [gpio_shared_proxy] #5: ffff0001f180ee90 (&gdev->srcu){.+.?}-{0:0}, at: gpiod_direction_output_raw_commit+0x0/0x360 irq event stamp: 81450 hardirqs last enabled at (81449): [<ffff8000813acba4>] _raw_spin_unlock_irqrestore+0x74/0x78 hardirqs last disabled at (81450): [<ffff8000813abfb8>] _raw_spin_lock_irqsave+0x84/0x88 softirqs last enabled at (79616): [<ffff8000811455fc>] __alloc_skb+0x17c/0x1e8 softirqs last disabled at (79614): [<ffff8000811455fc>] __alloc_skb+0x17c/0x1e8 CPU: 2 UID: 0 PID: 12 Comm: kworker/u16:0 Not tainted 6.19.0-rc4-next-20260105+ #11975 PREEMPT Hardware name: Hardkernel ODROID-M1 (DT) Workqueue: events_unbound deferred_probe_work_func Call trace: show_stack+0x18/0x24 (C) dump_stack_lvl+0x90/0xd0 dump_stack+0x18/0x24 __might_resched+0x144/0x248 __might_sleep+0x48/0x98 __mutex_lock+0x5c/0x894 mutex_lock_nested+0x24/0x30 pinctrl_get_device_gpio_range+0x44/0x128 pinctrl_gpio_direction+0x3c/0xe0 pinctrl_gpio_direction_output+0x14/0x20 rockchip_gpio_direction_output+0xb8/0x19c gpiochip_direction_output+0x38/0x94 gpiod_direction_output_raw_commit+0x1d8/0x360 gpiod_direction_output_nonotify+0x7c/0x230 gpiod_direction_output+0x34/0xf8 gpio_shared_proxy_direction_output+0xec/0x144 [gpio_shared_proxy] gpiochip_direction_output+0x38/0x94 gpiod_direction_output_raw_commit+0x1d8/0x360 gpiod_direction_output_nonotify+0x7c/0x230 gpiod_configure_flags+0xbc/0x480 gpiod_find_and_request+0x1a0/0x574 gpiod_get_index+0x58/0x84 devm_gpiod_get_index+0x20/0xb4 devm_gpiod_get_optional+0x18/0x30 rockchip_pcie_probe+0x98/0x380 platform_probe+0x5c/0xac really_probe+0xbc/0x298 Fixes: 936ee2675eee ("gpio/rockchip: add driver for rockchip gpio") Cc: stable(a)vger.kernel.org Reported-by: Marek Szyprowski <m.szyprowski(a)samsung.com> Closes: https://lore.kernel.org/all/d035fc29-3b03-4cd6-b8ec-001f93540bc6@samsung.co… Acked-by: Heiko Stuebner <heiko(a)sntech.de> Link: https://lore.kernel.org/r/20260106090011.21603-1-bartosz.golaszewski@oss.qu… Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski(a)oss.qualcomm.com> diff --git a/drivers/gpio/gpio-rockchip.c b/drivers/gpio/gpio-rockchip.c index 47174eb3ba76..bae2061f15fc 100644 --- a/drivers/gpio/gpio-rockchip.c +++ b/drivers/gpio/gpio-rockchip.c @@ -593,6 +593,7 @@ static int rockchip_gpiolib_register(struct rockchip_pin_bank *bank) gc->ngpio = bank->nr_pins; gc->label = bank->name; gc->parent = bank->dev; + gc->can_sleep = true; ret = gpiochip_add_data(gc, bank); if (ret) {
