Pull xen fixes from Juergen Gross:
 "Fixes and simple cleanups:

   - use a proper flexible array instead of a one-element array in order
     to avoid array-bounds sanitizer errors

   - add NULL pointer checks after allocating memory

   - use memdup_array_user() instead of open-coding it

   - fix a rare race condition in Xen event channel allocation code

   - make struct bus_type instances const

   - make kerneldoc inline comments match reality"
