Merge tag 's390-5.2-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - 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.
