0004 Description:
0005 This file allows the driver for a device to be specified which
0006 will override standard static and dynamic ID matching. When
0007 specified, only a driver with a name matching the value written
0008 to driver_override will have an opportunity to bind to the
0009 device. The override is specified by writing a string to the
0010 driver_override file (echo uio_hv_generic > driver_override) and
0011 may be cleared with an empty string (echo > driver_override).
0012 This returns the device to standard matching rules binding.
0013 Writing to driver_override does not automatically unbind the
0014 device from its current driver or make any attempt to
0015 automatically load the specified driver. If no driver with a
0016 matching name is currently loaded in the kernel, the device
0017 will not bind to any driver. This also allows devices to
0018 opt-out of driver binding using a driver_override name such as
0019 "none". Only a single driver may be specified in the override,
0020 there is no support for parsing delimiters.
