    Subject[PATCH 5.11 403/775] i3c/master/mipi-i3c-hci: Specify HAS_IOMEM dependency
    Date
    From: David Gow <davidgow@google.com>

    [ Upstream commit 9d909f1b1e91b4aa7d016ed14b7b76dbf2675414 ]

    The MIPI i3c HCI driver makes use of IOMEM functions like
    devm_platform_ioremap_resource(), which are only available if
    CONFIG_HAS_IOMEM is defined.

    This causes the driver to be enabled under make ARCH=um allyesconfig,
    even though it won't build.

    By adding a dependency on HAS_IOMEM, the driver will not be enabled on
    architectures which don't support it.
