Subject: [PATCH] PCI: xgene: Annotate __iomem pointer
Date: Mon, 17 May 2021 12:18:39 -0500	[thread overview]
Message-ID: <> (raw)

From: Bjorn Helgaas <>

"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.
