From 0636bab67fa4df68c85b28ba345596a72986fa9e Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 10 Feb 2016 15:46:58 +0100 Subject: [PATCH] irqchip/armada-370-xp: Use PCI_MSI_DOORBELL_START where appropriate As suggested by Gregory Clement, this commit adjusts the irq-armada-370-xp driver to use the PCI_MSI_DOORBELL_START define in the armada_370_xp_handle_msi_irq() function, rather than hardcoding its value.
