| Date: August 2019 |

| Description: |
| This file allows the driver for a device to be specified which |
| will override standard static and dynamic ID 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 uio_hv_generic > driver_override) and |
| may be cleared with an empty string (echo > driver_override). |
| This 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. |
