Subject: [GIT pull] irq/urgent for v5.16-rc5
Linus,
please pull the latest irq/urgent branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-2021-12-12
up to: b7fd35a0ad97: Merge tag 'irqchip-fixes-5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
A set of interrupt chip driver fixes:
- Fix the multi vector MSI allocation on Armada 370XP.
- Do interrupt acknowledgement correctly in the aspeed-scu driver.
- Make the IPR register offset correct in the NVIC driver.
- Make redistribution table flushing correct by issueing a SYNC command to
ensure that the invalidation command has been executed.
- Plug a device tree node reference leak in the bcm7210-l2 driver.
- Trivial fixes in the MIPS GIC and the Apple AIC drivers
Thanks,
tglx
