Subject: [GIT pull] irq fix for 4.17
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 single fix to prevent false positives in the spurious interrupt detector
when more than a single demultiplex register is evaluated in the Qualcom
irq combiner driver.
Thanks,
tglx
