    Subject[PATCH v3 18/20] spi: Remove depends on HAS_DMA in case of platform dependency
    Date
    Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
    symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
    In most cases this other symbol is an architecture or platform specific
    symbol, or PCI.

    Generic symbols and drivers without platform dependencies keep their
    dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
    cannot work anyway.

    This simplifies the dependencies, and allows to improve compile-testing.
