-Subject: [PATCH 24/96] PCI: aardvark: Add suspend to RAM support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add suspend and resume callbacks. We need to use the NOIRQ variants to
-ensure the controller's IRQ handlers are not run during suspend() /
-resume(), which could cause races.
