spi: spidev: Add SPI ID table
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") Signed-off-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20210923170023.1683-1-broonie@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>
