+What:		/sys/bus/wmi/devices/.../driver_override
+Date:		February 2024
+Contact:	Armin Wolf <[email protected]>
+Description:
+		This file allows the driver for a device to be specified which
+		will override standard ID table matching.
+		When specified, only a driver with a name matching the value
+		written to driver_override will have an opportunity to bind
+		to the device.
+		The override is specified by writing a string to the
+		driver_override file (echo wmi-event-dummy > driver_override).
+		The override may be cleared with an empty string (echo > \
+		driver_override) which returns the device to standard matching
+		rules binding.
+		Writing to driver_override does not automatically unbind the
+		device from its current driver or make any attempt to automatically
+		load the specified driver. If no driver with a matching name is
+		currently loaded in the kernel, the device will not bind to any
+		driver.
+		This also allows devices to opt-out of driver binding using a
+		driver_override name such as "none". Only a single driver may be
+		specified in the override, there is no support for parsing delimiters.
