/*
* Check the mode that the given bi-modal CXL adapter is currently in and
* change it if necessary. This does not apply to AFU drivers.
*
* If the mode matches the requested mode this function will return 0 - if the
* driver was expecting the generic CXL driver to have bound to the adapter and
* it gets this return value it should fail the probe function to give the CXL
* driver a chance to probe it.
*
* If the mode does not match it will start a background task to unplug the
* device from Linux and switch its mode, and will return -EBUSY. At this
* point the calling driver should make sure it has released the device and
* fail its probe function.
*
* The offset of the CXL VSEC can be provided to this function. If 0 is passed,
* this function will search for a CXL VSEC with ID 0x1280 and return -ENODEV
* if it is not found.
