From 283026528e0ee8ea89a60f9addaf0f2eda167c42 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 21 Sep 2022 16:36:18 +0000 Subject: [PATCH] iio: adc: ad9467: Silence no spi_device_id warnings 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 ad9467 has no spi_device_id for adi,ad9265 SPI driver ad9467 has no spi_device_id for adi,ad9434 Add spi_device_id entries to silence the warnings, and ensure driver module autoloading works.
