From 3df2ebcee9fb3bd2597d1758795471a3a3b2203c Mon Sep 17 00:00:00 2001 From: Wei Wang Date: Tue, 13 May 2025 11:07:38 +0800 Subject: [PATCH] iommu/vt-d: Eliminate pci_physfn() in dmar_find_matched_satc_unit() The function dmar_find_matched_satc_unit() contains a duplicate call to pci_physfn(). This call is unnecessary as pci_physfn() has already been invoked by the caller. Removing the redundant call simplifies the code and improves efficiency a bit.
