2024-05-04driver core: Add device_show_string() helper for sysfs attributesLukas Wunner
For drivers wishing to expose an unsigned long, int or bool at a static memory location in sysfs, the driver core provides ready-made helpers such as device_show_ulong() to be used as ->show() callback. Some drivers need to expose a string and so far they all provide their own ->show() implementation. arch/powerpc/perf/hv-24x7.c went so far as to create a device_show_string() helper but kept it private. Make it public for reuse by other drivers. The pattern seems to be sufficiently frequent to merit a public helper. Add a DEVICE_STRING_ATTR_RO() macro in line with the existing DEVICE_ULONG_ATTR() and similar macros to ease declaration of string attributes.

2024-05-04hwmon: (corsair-cpro) Protect ccp->wait_input_report with a spinlockAleksa Savic
Through hidraw, userspace can cause a status report to be sent from the device. The parsing in ccp_raw_event() may happen in parallel to a send_usb_cmd() call (which resets the completion for tracking the report) if it's running on a different CPU where bottom half interrupts are not disabled. Add a spinlock around the complete_all() in ccp_raw_event() and reinit_completion() in send_usb_cmd() to prevent race issues.

ccp_raw_event() In ccp_raw_event(), the ccp->wait_input_report completion is completed once.

2024-05-04hwmon: (corsair-cpro) Use a separate buffer for sending commandsAleksa Savic
Introduce cmd_buffer, a separate buffer for storing only the command that is sent to the device. Before this separation, the existing buffer was shared for both the command and the report received in ccp_raw_event(), which was copied into it. However, because of hidraw, the raw event parsing may be triggered in the middle of sending a command, resulting in outputting gibberish to the device. Using a separate buffer resolves this.

2024-05-04dmaengine: idxd: Avoid unnecessary destruction of file_idaFenghua Yu
file_ida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to destroy an already empty file_ida when the WQ cdev is removed. Worse, ida_free() in cdev release may happen after destruction of file_ida per WQ cdev. This can lead to accessing an id in file_ida after it has been destroyed, resulting in a kernel panic. Remove ida_destroy(&file_ida) to address these issues.

2024-05-04watchdog: bd9576: Drop "always-running" propertyMatti Vaittinen
The always-running (from linux,wdt-gpio.yaml) is abused by the BD9576 watchdog driver. It's defined meaning is "the watchdog is always running and can not be stopped". The BD9576 watchdog driver has implemented it as "start watchdog when loading the module and prevent it from being stopped". Furthermore, the implementation does not set the WDOG_HW_RUNNING when enabling the watchdog due to the "always-running" at module loading. This will end up resulting a watchdog timeout if the device is not opened.
