From 0b74ecdfbea893ae585bc694136a3f50f5856cfe Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 6 Apr 2016 21:38:56 +0300 Subject: iommu/vt-d: Silence an uninitialized variable warning My static checker complains that "dma_alias" is uninitialized unless we are dealing with a pci device. This is true but harmless. Anyway, we can flip the condition around to silence the warning.
