    Subject[PATCH AUTOSEL 5.4 010/187] spi: fsl: Fix GPIO descriptor support
    Date
    From: Linus Walleij <linus.walleij@linaro.org>

    [ Upstream commit f106904968e2a075e64653b9b79dda9f0f070ab5 ]

    This makes the driver actually support looking up GPIO
    descriptor. A coding mistake in the initial descriptor
    support patch was that it was failing to turn on the very
    feature it was implementing. Mea culpa.
