From: Kim Phillips <kim.phillips@xxxxxxxxxx> Needed by drivers, such as the vfio platform driver [1], seeking to bypass bind_store()'s driver_match_device(), and bind to any device via a private sysfs bind file. [1] https://lkml.org/lkml/2013/12/11/522 note: the EXPORT_SYMBOL is needed because vfio-platform can be built as a module.
