Subject: [PATCH 4/8] grub-core/bus/usb: Add function pointer for attach/detach
|
|
events
|
|
|
|
The xHCI code needs to be called for attaching or detaching a device.
|
|
Introduce two functions pointers and call it from the USB hub code.
|
|
|
|
Will be used in future commits, currently this doesn't change any functionality.
