[PATCH v2 06/10] drm/panel: s6d27a1: Silence no spi_device_id warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

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 s6d27a1-panel has no spi_device_id for samsung,s6d27a1

Add spi_device_id entries to silence the warning, and ensure driver
module autoloading works.
