From 31ea5d4dfe21fb50276dcd70ce268e58d57eccb4 Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Thu, 19 Jun 2014 16:30:30 +0800 Subject: [PATCH] PCI/MSI: Cache Multiple Message Capable in struct msi_desc The Multiple Message Capable field in the MSI Message Control register indicates how many vectors the device supports. This field is read-only, so cache it in msi_desc to avoid reading it repeatedly. Since we cache the extracted field (not the entire Message Control register), we can use msi_mask() instead of msi_capable_mask(), which is then unused, so remove it.
