Merge tag 'timers-urgent-2025-07-27' of git://git.kernel.org/pub/scm/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"
