From 48c3c38f003c25d50a09d3da558667c5ecd530aa Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Tue, 23 Sep 2014 11:02:42 -0600 Subject: PCI/MSI: Remove "pos" from the struct msi_desc msi_attrib "msi_attrib.pos" is only used for MSI (not MSI-X), and we already cache the MSI capability offset in "dev->msi_cap". Remove "pos" from the struct msi_attrib and use "dev->msi_cap" directly.
