  vfio-ccw: Destroy kmem cache region on module exit (2019-06-13 15:52:28 +0200)

----------------------------------------------------------------
s390 updates for 5.2-rc6

 - Disable address-of-packed-member warning in s390 specific boot code
   to get rid of a gcc9 warning which otherwise is already disabled
   for the whole kernel.

 - Fix yet another compiler error seen with CONFIG_OPTIMIZE_INLINING
   enabled.

 - Fix memory leak in vfio-ccw code on module exit.
