4Description:
5		This file allows the driver for a device to be specified which
6		will override standard OF, ACPI, ID table, and name matching.
7		When specified, only a driver with a name matching the value
8		written to driver_override will have an opportunity to bind
9		to the device.  The override is specified by writing a string
10		to the driver_override file (echo vfio-platform > \
11		driver_override) and may be cleared with an empty string
12		(echo > driver_override).  This returns the device to standard
13		matching rules binding.  Writing to driver_override does not
14		automatically unbind the device from its current driver or make
15		any attempt to automatically load the specified driver.  If no
16		driver with a matching name is currently loaded in the kernel,
17		the device will not bind to any driver.  This also allows
18		devices to opt-out of driver binding using a driver_override
19		name such as "none".  Only a single driver may be specified in
20		the override, there is no support for parsing delimiters.
