The sparse checker complains about converting pointers between address spaces. The pci_config_window.priv pointer is a generic void *, but hisi_pcie_map_bus() needs a void __iomem *. This isn't a problem in other drivers because they store the __iomem pointer in a driver struct. Add a trivial struct hisi_pcie to avoid the warning. The sparse warning looks like this: $ make C=2 drivers/pci/controller/ drivers/pci/controller/dwc/pcie-hisi.c:61:37: warning: incorrect type in initializer (different address spaces) drivers/pci/controller/dwc/pcie-hisi.c:61:37: expected void [noderef] __iomem *reg_base drivers/pci/controller/dwc/pcie-hisi.c:61:37: got void *priv Link: https://lore.kernel.org/r/20211223213749.1314142-2-helgaas@kernel.org Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Cc: Zhou Wang <wangzhou1@hisilicon.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
