Merge tag 'irq_urgent_for_v6.13_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq fixes from Borislav Petkov:

 - Move the ->select callback to the correct ops structure in
   irq-mvebu-sei to fix some Marvell Armada platforms

 - Add a workaround for Hisilicon ITS erratum 162100801 which can cause
   some virtual interrupts to get lost

 - More platform_driver::remove() conversion

* tag 'irq_urgent_for_v6.13_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  irqchip: Switch back to struct platform_driver::remove()
  irqchip/gicv3-its: Add workaround for hip09 ITS erratum 162100801
  irqchip/irq-mvebu-sei: Move misplaced select() callback to SEI CP domain
