[GIT pull] timers/clocksource for v7.3-rc1

Linus,

please pull the latest timers/clocksource branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-clocksource-2026-08-17

up to:  0eaed89c18ae: Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource

Clocksource/event driver updates:

  - Remove redundant dev_err() and dev_err_probe() invocations in various
    drivers.

  - Handle SWAP_IO_SPACE correctly in the rtl-otto driver

  - Make the Samsumg PWM timer driver PREEMPT_RT compatible

  - Ensure that the SUN4I timer is programmed with a delta larger than zero
    as a zero delta causes the the timer to be disabled.

  - The usual fixes and improvements all over the place

Thanks,

	tglx
