    Subject[PATCH 5.18 0692/1095] mtd: dataflash: Add SPI ID table
    Date
    From: Mark Brown <broonie@kernel.org>

    [ Upstream commit ac4f83482afbfd927d0fe118151b747cf175e724 ]

    Currently autoloading for SPI devices does not use the DT ID table, it uses
    SPI modalises. Supporting OF modalises is going to be difficult if not
    impractical, an attempt was made but has been reverted, so ensure that
    module autoloading works for this driver by adding an id_table listing the
    SPI IDs for everything.

    Fixes: 96c8395e2166 ("spi: Revert modalias changes")
