2025-07-22PCI/pwrctrl: Create pwrctrl devices only when CONFIG_PCI_PWRCTRL is enabledManivannan Sadhasivam
If devicetree describes power supplies related to a PCI device, we unnecessarily created a pwrctrl device even if CONFIG_PCI_PWRCTL was not enabled. We only need pci_pwrctrl_create_device() when CONFIG_PCI_PWRCTRL is enabled. Compile it out when CONFIG_PCI_PWRCTRL is not enabled. When pci_pwrctrl_create_device() creates and returns a pwrctrl device, pci_scan_device() doesn't enumerate the PCI device. It assumes the pwrctrl core will rescan the bus after turning on the power. However, if CONFIG_PCI_PWRCTRL is not enabled, the rescan never happens, which breaks PCI enumeration on any system that describes power supplies in devicetree but does not use pwrctrl. Jim reported that some brcmstb platforms break this way. The brcmstb driver is still broken if CONFIG_PCI_PWRCTRL is enabled, but this commit at least allows brcmstb to work when it's NOT enabled.

2025-07-22vt: defkeymap: Map keycodes above 127 to K_HOLEMyrrh Periwinkle
The maximum number of keycodes got bumped to 256 a very long time ago, but the default keymaps were never adjusted to match. This is causing the kernel to interpret keycodes above 127 as U+0000 if the shipped generated keymap is used. Fix this by mapping all keycodes above 127 to K_HOLE so the kernel ignores them. The contents of this patche were generated by rerunning `loadkeys --mktable --unicode` and only including the changes to map keycodes above 127 to K_HOLE.

2025-07-22serial: qcom-geni: Enable Serial on SA8255p Qualcomm platformsPraveen Talari
The Qualcomm automotive SA8255p SoC relies on firmware to configure platform resources, including clocks, interconnects and TLMM. The driver requests resources operations over SCMI using power and performance protocols. The SCMI power protocol enables or disables resources like clocks, interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs, such as resume/suspend, to control power states(on/off). The SCMI performance protocol manages UART baud rates, with each baud rate represented by a performance level. The driver uses the dev_pm_opp_set_level() API to request the desired baud rate by specifying the performance level.

2025-07-22serial: qcom-geni: Enable PM runtime for serial driverPraveen Talari
The GENI serial driver currently handles power resource management through calls to the statically defined geni_serial_resources_on() and geni_serial_resources_off() functions. This approach reduces modularity and limits support for platforms with diverse power management mechanisms, including resource managed by firmware. Improve modularity and enable better integration with platform-specific power management, introduce support for runtime PM. Use pm_runtime_resume_and_get() and pm_runtime_put_sync() within the qcom_geni_serial_pm() callback to control resource power state transitions based on UART power state changes.

2025-07-22comedi: fix race between polling and detachingIan Abbott
syzbot reports a use-after-free in comedi in the below link, which is due to comedi gladly removing the allocated async area even though poll requests are still active on the wait_queue_head inside of it. This can cause a use-after-free when the poll entries are later triggered or removed, as the memory for the wait_queue_head has been freed. We need to check there are no tasks queued on any of the subdevices' wait queues before allowing the device to be detached by the `COMEDI_DEVCONFIG` ioctl. Tasks will read-lock `dev->attach_lock` before adding themselves to the subdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctl handler by write-locking `dev->attach_lock` before checking that all of the subdevices are safe to be deleted. This includes testing for any sleepers on the subdevices' wait queues. It remains locked until the device has been detached. This requires the `comedi_device_detach()` function to be refactored slightly, moving the bulk of it into new function `comedi_device_detach_locked()`. Note that the refactor of `comedi_device_detach()` results in `comedi_device_cancel_all()` now being called while `dev->attach_lock` is write-locked, which wasn't the case previously, but that does not matter. Thanks to Jens Axboe for diagnosing the problem and co-developing this patch.

2025-07-22fs/orangefs: Allow 2 more characters in do_c_string()Dan Carpenter
The do_k_string() and do_c_string() functions do essentially the same thing which is they add a string and a comma onto the end of an existing string. At the end, the caller will overwrite the last comma with a newline. Later, in orangefs_kernel_debug_init(), we add a newline to the string. The change to do_k_string() is just cosmetic. I moved the "- 1" to the other side of the comparison and made it "+ 1". This has no effect on runtime, I just wanted the functions to match each other and the rest of the file. However in do_c_string(), I removed the "- 2" which allows us to print two extra characters. I noticed this issue while reviewing the code and I doubt affects anything in real life. My guess is that this was double counting the comma and the newline. The "+ 1" accounts for the newline, and the caller will delete the final comma which ensures there is enough space for the newline. Removing the "- 2" lets us print 2 more characters, but mainly it makes the code more consistent and understandable for reviewers.

2025-07-22sunvdc: Balance device refcount in vdc_port_mpgroup_checkMa Ke
Using device_find_child() to locate a probed virtual-device-port node causes a device refcount imbalance, as device_find_child() internally calls get_device() to increment the device’s reference count before returning its pointer. vdc_port_mpgroup_check() directly returns true upon finding a matching device without releasing the reference via put_device(). We should call put_device() to decrement refcount. As comment of device_find_child() says, 'NOTE: you will need to drop the reference with put_device() after use'. Found by code review.

To fix this issue, let's add sanity check for node id of all direct nodes during f2fs_get_dnode_of_data().

2025-07-22f2fs: switch to the new mount apiHongbo Li
The new mount api will execute .parse_param, .init_fs_context, .get_tree and will call .remount if remount happened. So we add the necessary functions for the fs_context_operations. If .init_fs_context is added, the old .mount should remove. See Documentation/filesystems/mount_api.rst for more information.

2025-07-22f2fs: separate the options parsing and options checkingHongbo Li
The new mount api separates option parsing and super block setup into two distinct steps and so we need to separate the options parsing out of the parse_options(). In order to achieve this, here we handle the mount options with three steps: - Firstly, we move sb/sbi out of handle_mount_opt. As the former patch introduced f2fs_fs_context, so we record the changed mount options in this context. In handle_mount_opt, sb/sbi is null, so we should move all relative code out of handle_mount_opt (thus, some check case which use sb/sbi should move out). - Secondly, we introduce the some check helpers to keep the option consistent. During filling superblock period, sb/sbi are ready. So we check the f2fs_fs_context which holds the mount options base on sb/sbi. - Thirdly, we apply the new mount options to sb/sbi. After checking the f2fs_fs_context, all changed on mount options are valid. So we can apply them to sb/sbi directly. After do these, option parsing and super block setting have been decoupled. Also it should have retained the original execution flow.

2025-07-22f2fs: Add f2fs_fs_context to record the mount optionsHongbo Li
At the parsing phase of mouont in the new mount api, options value will be recorded with the context, and then it will be used in fill_super and other helpers. Note that, this is a temporary status, we want remove the sb and sbi usages in handle_mount_opt. So here the f2fs_fs_context only records the mount options, it will be copied in sb/sbi in later process. (At this point in the series, mount options are temporarily not set during mount.)

2025-07-22f2fs: move the option parser into handle_mount_optHongbo Li
In handle_mount_opt, we use fs_parameter to parse each option. However we're still using the old API to get the options string. Using fsparams parse_options allows us to remove many of the Opt_ enums, so remove them. The checkpoint disable cap (or percent) involves rather complex parsing; we retain the old match_table mechanism for this, which handles it well. There are some changes about parsing options: 1. For `active_logs`, `inline_xattr_size` and `fault_injection`, we use s32 type according the internal structure to record the option's value.
