Merge tag 'irq-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull generic interrupt subsystem updates from Thomas Gleixner:

 - Remove pointless NULL checks of the kstats_irqs field. That's a
   historical left over and not longer required.

 - Add Radu Rendec as reviewer. Radu thankfully stepped up to help
   reviewing the interrupt core and the related drivers code.

 - The usual small improvements and fixes
