From 662e4b03431f5304603f1e42c4d4c2c1d64cba40 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 17 May 2021 12:18:39 -0500 Subject: [PATCH] PCI: xgene: Annotate __iomem pointer "bar_addr" is passed as the argument to writel(), which expects a "void __iomem *". Annotate "bar_addr" correctly. Resolves an sparse "incorrect type in argument 2 (different address spaces)" warning.
