  s390/stacktrace: Do not fallback to RA register (2025-12-14 11:03:58 +0100)

----------------------------------------------------------------
s390 fixes for 6.19-rc2

- clear 'Search boot program' flag when 'bootprog' sysfs file is
  written to override a value set from Hardware Management Console

- fix cyclic dead-lock in zpci_zdev_put() and zpci_scan_devices()
  functions when triggering PCI device recovery using sysfs

- annotate the expected lock context imbalance in zpci_release_device()
  function to fix a sparse complaint

- fix the logic to fallback to the return address register value in
  the topmost frame when stack tracing uses a back chain
