    Subject[PATCH AUTOSEL 5.12 03/79] spi: ath79: always call chipselect function
    Date
    From: David Bauer <mail@david-bauer.net>

    [ Upstream commit 19e2132174583beb90c1bd3e9c842bc6d5c944d1 ]

    spi-bitbang has to call the chipselect function on the ath79 SPI driver
    in order to communicate with the SPI slave device, as the ath79 SPI
    driver has three dedicated chipselect lines but can also be used with
    GPIOs for the CS lines.

    Fixes commit 4a07b8bcd503 ("spi: bitbang: Make chipselect callback optional")
