Merge tag 'timers-v6.11-rc7' of https://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
Pull clocksource driver fixes from Daniel Lezcano: - Remove percpu irq related code in the timer-of initialization routine as it is broken but also unused (Daniel Lezcano) - Fix return -ETIME when delta exceeds INT_MAX and the next event not taking effect sometimes (Jacky Bai) Link: https://lore.kernel.org/all/d0e93dbd-b796-4726-b38c-089b685591c9@linaro.org
