From 6c206e4d99f2ed2a5a59875858e3beecc69b6474 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 16 Dec 2016 14:28:40 +0100 Subject: [PATCH] x86, swiotlb: Simplify pci_swiotlb_detect_override() At the end of the function, the local variable use_swiotlb has always the same value as the global variable swiotlb. Hence drop the local variable completely.
