Subject: [PATCH 07/18] Delayed cris setup of PCI IRQs to bus scan time
Date: Thu,  2 Oct 2014 05:07:35 +0100	[thread overview]
Message-ID: <1412222866-21068-8-git-send-email-matt@masarand.com> (raw)
In-Reply-To: <1412222866-21068-1-git-send-email-matt@masarand.com>

From: Matthew Minter <matt@masarand.com>

PCI IRQs are currently configured to be enabled once at boot in a
dedicated pass. This means that PCI devices which are hot-plugged after
boot time will not be given an IRQ, this patch-set fixes this by
registering the assignment function to be called later in the device
enable path.
