[GIT pull] irq updates for 4.19
From: Thomas Gleixner
Date: Sun Aug 26 2018 - 05:39:26 EST
Linus,
please pull the latest irq-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-for-linus
A small set of updats/fixes for the irq subsystem:
- Allow GICv3 interrupts to be configured as wake-up sources to enable
wakeup from suspend
- Make the error handling of the STM32 irqchip init function work
- A set of small cleanups and improvements
Thanks,
tglx
