[PATCH AUTOSEL 4.19 11/17] mmc: spi: Add device-tree SPI IDs

From: Sasha Levin <sashal@kernel.org>
Date: 2021-11-30 15:07:58
Also in: lkml, stable
Subsystem: multimedia card (mmc) etc. over spi, multimedia card (mmc), secure digital (sd) and sdio subsystem, the rest · Maintainers: Ulf Hansson, Linus Torvalds

From: Jon Hunter <jonathanh@nvidia.com>

[ Upstream commit 5f719948b5d43eb39356e94e8d0b462568915381 ]

Commit 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_id is
missing for the MMC SPI driver and the following warning is now seen.

 WARNING KERN SPI driver mmc_spi has no spi_device_id for mmc-spi-slot

Fix this by adding the necessary spi_device_id.
