    Subject[PATCH 6.0 442/862] soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA
    Date
    From: Dmitry Osipenko <digetx@gmail.com>

    [ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ]

    The DMA subsystem could be entirely disabled in Kconfig and then the
    TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
    fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
    dependency.

    The FUSE driver isn't a critical driver and currently it only provides
    NVMEM interface to userspace which isn't known to be widely used, and
    thus, it's fine if FUSE driver fails to load.

    Let's remove the erroneous Kconfig dependency and let the FUSE driver to
    fail the probing if DMA is unavailable.

    Fixes: 19d41e5e9c68 ("soc/tegra: fuse: Add APB DMA dependency for Tegra20")
