From 2af5066f664cb011cf17d2e4414491fe24597e07 Mon Sep 17 00:00:00 2001 From: Hidetoshi Seto Date: Thu, 18 Jun 2009 19:20:26 -0700 Subject: [PATCH] PCI: make msi_free_irqs() to use msix_mask_irq() instead of open coded write Use msix_mask_irq() instead of direct use of writel, so as not to clear preserved bits in the Vector Control register [31:1].
