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