Subject: [PATCH] gpio: 74x164: Add SPI device ID table
Git-commit: be4491838359e78e42e88db4ac479e21c5eda1e0
Patch-mainline: v5.15-rc6
References: git-fixes stable-5.14.14
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 a SPI device ID table.
Fixes: 96c8395e2166 ("spi: Revert modalias changes")
