Merge tag 'timers-urgent-2025-07-27' of git://git./linux/kernel/git/tip/tip

Pull timer fix from Thomas Gleixner:
 "A single fix for the PTP systemcounter mechanism:

  The rework of this mechanism added a 'use_nsec' member to struct
  system_counterval. get_device_system_crosststamp() instantiates that
  struct on the stack and hands a pointer to the driver callback.

  Only the drivers which set use_nsec to true, initialize that field,
  but all others ignore it. As get_device_system_crosststamp() does not
  initialize the struct, the use_nsec field contains random stack
  content in those cases. That causes a miscalulation usually resulting
  in a failing range check in the best case.

  Initialize the structure before handing it to the drivers to cure
  that"
