Subject: [PATCH] vfio/pci: Fix sparse warning in vfio_pci_core_get_iomap()
Date: Fri, 22 May 2026 05:42:11 -0700	[thread overview]
Message-ID: <20260522124215.3268565-1-mattev@meta.com> (raw)

Use IOMEM_ERR_PTR() when returning a void __iomem * rather than
ERR_PTR().  This fixes a sparse warning, "different address spaces".

Fixes: 859dc0f6253b ("vfio/pci: Replace vfio_pci_core_setup_barmap() with vfio_pci_core_get_iomap()")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202605211601.U1OvmuqY-lkp@intel.com/
