> Clockevent devices belonging to different CPUs can share the same
> name. The sysfs unbind handler selects the first matching name from
> the global device list, which can cause a request for one CPU to
> unbind another CPU's device or incorrectly return -EBUSY.
>
> Check the device's CPU mask when selecting the clockevent to unbind
> so that the request targets a device eligible for the specified CPU.
