    Subject[PATCH 4.20 103/352] spi: fix spi-at91-usart.c build errors when PINCTRL is not set
    Date
    4.20-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    [ Upstream commit c2b142cc3939e932d4fa2210c2a5155df5736590 ]

    Fix build errors when CONFIG_PINCTRL is not enabled.
    The header file <linux/pinctrl/consumer.h> handles both CONFIG_PINCTRL
    enabled and disabled cases.
