Subject: [GIT pull] irq fix for 4.12
Date: Sun, 18 Jun 2017 11:22:40 +0200 (CEST)	[thread overview]
Message-ID: <alpine.DEB.2.20.1706181121270.2428@nanos> (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 fix, which adds a missing resource release to an error path.

Thanks,

	tglx
