    Subject[PATCH 5.4 094/165] staging: axis-fifo: add unspecified HAS_IOMEM dependency
    Date
    From: Brendan Higgins <brendanhiggins@google.com>

    [ Upstream commit d3aa8de6b5d0853c43c616586b4e232aa1fa7de9 ]

    Currently CONFIG_XIL_AXIS_FIFO=y implicitly depends on
    CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
    the following build error:

    ld: drivers/staging/axis-fifo/axis-fifo.o: in function `axis_fifo_probe':
    drivers/staging/axis-fifo/axis-fifo.c:809: undefined reference to `devm_ioremap_resource'

    Fix the build error by adding the unspecified dependency.
