  xen: use static initializers in xen-balloon.c
  Xen: fix braces and tabs coding style issue in xenbus_probe.c
  Xen: fix braces coding style issue in xenbus_probe.h
  Xen: fix whitespaces,tabs coding style issue in drivers/xen/pci.c
  Xen: fix braces coding style issue in gntdev.c and grant-table.c
  Xen: fix whitespaces,tabs coding style issue in drivers/xen/events.c
  Xen: fix whitespaces,tabs coding style issue in drivers/xen/balloon.c

Fix up trivial whitespace-conflicts in
 drivers/xen/{balloon.c,pci.c,xenbus/xenbus_probe.c}
