From: Wei Yongjun <[email protected]> SPI devices use the spi_device_id for module autoloading even on systems using device tree, after commit 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT compatible"), kernel warns as follows since the spi_device_id is missing:
SPI driver ws2401-panel has no spi_device_id for samsung,lms380kf01 Add spi_device_id entries to silence the warning, and ensure driver module autoloading works.
