2025-09-07hwmon: (ltc4282) remove the use of dev_err_probe()Liao Yuanhong
Logging messages that show some type of "out of memory" error are generally unnecessary as there is a generic message and a stack dump done by the memory subsystem. These messages generally increase kernel size without much added value[1]. The dev_err_probe() doesn't do anything when error is '-ENOMEM'. Therefore, remove the useless call to dev_err_probe(), and just return the value instead.

Add support for SPD, AUDIO, DRM and HDMI InfoFrames. Also add support for ISRC1 and ISRC2 Packet Types and a programmable type for both Packet and InfoFrames. The tc358743 HDMI-to-CSI2 bridge is widely available, and it has quite flexible InfoFrame/Packet Type support, so this makes it a very nice device to capture such data. The ACP (Audio Content Protection) Packet capture data is chosen as the programmable type. ACP is typically only used for protected audio, which is quite rare, so instead it is reprogrammed to capture DRM InfoFrames by default. This can be changed by using the packet_type module option to anything you want, and you can change it on the fly as well. It will be updated whenever VIDIOC_LOG_STATUS is called (it's really a debug feature). Tested on my Raspberry Pi 5.

2025-09-06power: supply: 88pm860x: make fsm_state array static const, simplify usageColin Ian King
Don't populate the read-only array fsm_state on the stack at run time, instead make it static const, this reduces the object code size as the data is placed on the data segment and this removes the need to have code to set the array up on each call. Note that making the size of the strings to a more optimal 11 bytes long does not seem to reduce the overall size. Making the array an array of pointers to the strings increases the code size due to the dereferencing overhead. Simplify the array access with &fsm_state[info->state][0] with the simpler expression fsm_state[info->state] to clean up the code.

auxiliary_match_id() repeatedly calculates variable @match_size in the for loop, however, the variable is fixed actually, so it is enough to only calculate the variable once. Besides, the function should return directly if name of the @auxdev does not include '.', but it still iterates over the ID table. Additionally, statement 'dev_name(&auxdev->dev)' is fixed, but may be evaluated more than 3 times.

Starting with commit f99508074e78 ("PM: domains: Detach on device_unbind_cleanup()"), there is no longer a need to call dev_pm_domain_detach() in the bus remove function. The device_unbind_cleanup() function now handles this to avoid invoking devres cleanup handlers while the PM domain is powered off, which could otherwise lead to failures as described in the above-mentioned commit.

2025-09-06driver core: get_dev_from_fwnode(): document potential raceDanilo Krummrich
Commit 9a4681a485ee ("driver core: Export get_dev_from_fwnode()") made get_dev_from_fwnode() publicly available, but didn't document the guarantees a caller must uphold: get_dev_from_fwnode() obtains a reference count from the device pointer stored in a struct fwnode_handle. While having its own reference count, struct fwnode_handle does not keep a reference count of the device it has a pointer to. Consequently, a caller must guarantee that it is impossible that the last device reference is dropped and the device is released concurrently while calling get_dev_from_fwnode(), otherwise this is a potential UAF and hence a bug. Thus, document this potential race condition for get_dev_from_fwnode().

mei_device lifetime was managed by devm procedure of parent device. But such memory is freed on device_del. Mei_device object is used by client object that may be alive after parent device is removed.

2025-09-06char: Use list_del_init() in misc_deregister() to reinitialize list pointerXion Wang
Currently, misc_deregister() uses list_del() to remove the device from the list. After list_del(), the list pointers are set to LIST_POISON1 and LIST_POISON2, which may help catch use-after-free bugs, but does not reset the list head. If misc_deregister() is called more than once on the same device, list_empty() will not return true, and list_del() may be called again, leading to undefined behavior. Replace list_del() with list_del_init() to reinitialize the list head after deletion. This makes the code more robust against double deregistration and allows safe usage of list_empty() on the miscdevice after deregistration. [ Note, this seems to keep broken out-of-tree drivers from doing foolish things. While this does not matter for any in-kernel drivers, external drivers could use a bit of help to show them they shouldn't be doing stuff like re-registering misc devices - gregkh ] Signed-off-by: Xion Wang <xion.wang@mediatek.com> Link: https://lore.kernel.org/r/20250904063714.28925-2-xion.wang@mediatek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2025-09-06Input: mtk-pmic-keys - MT6359 has a specific release irqJulien Massot
Support for MT6359 PMIC keys has been added recently. However, the key release event is not properly handled: only key press events are generated, leaving key states stuck in "pressed". This patch ensures that both key press and key release events are properly emitted by handling the release logic correctly. Introduce a 'key_release_irq' member to the 'mtk_pmic_regs' to identify the devices that have a separate irq for the release event.

2025-09-07PM / devfreq: mtk-cci: Fix potential error pointer dereference in probe()Dan Carpenter
The drv->sram_reg pointer could be set to ERR_PTR(-EPROBE_DEFER) which would lead to a error pointer dereference. Use IS_ERR_OR_NULL() to check that the pointer is valid.

2025-09-06drm/msm: make sure to not queue up recovery more than onceAntonino Maniscalco
If two fault IRQs arrive in short succession recovery work will be queued up twice. When recovery runs a second time it may end up killing an unrelated context. Prevent this by masking off interrupts when triggering recovery.

The Adreno GPU Management Unit (GMU) can also scale DDR Bandwidth along the Frequency and Power Domain level, but by default we leave the OPP core scale the interconnect ddr path. Declare the Bus Control Modules (BCMs) and the corresponding parameters in the GPU info struct to allow the GMU to vote for the bandwidth.
