| parent | ptp/kvm, arm_arch_timer: Set system_counterval_t.cs_id to constant (diff) | |
timekeeping: Evaluate system_counterval_t.cs_id instead of .cs
Clocksource pointers can be problematic to obtain for drivers which are not
clocksource drivers themselves. In particular, the RFC virtio_rtc driver
[1] would require a new helper function to obtain a pointer to the ARM
Generic Timer clocksource. The ptp_kvm driver also required a similar
workaround.
Address this by evaluating the clocksource ID, rather than the clocksource
pointer, of struct system_counterval_t. By this, setting the clocksource
pointer becomes unneeded, and get_device_system_crosststamp() callers will
no longer need to supply clocksource pointers.
All relevant clocksource drivers provide the ID, so this change is not
changing the behaviour.
