Subject: [GIT pull] irq fix for 4.17
Date: Sun, 6 May 2018 09:54:59 +0200 (CEST)	[thread overview]
Message-ID: <alpine.DEB.2.21.1805060948550.1685@nanos.tec.linutronix.de> (raw)

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
