Subject[PATCH AUTOSEL 4.4 5/9] mmc: spi: Add device-tree SPI IDs
Date
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.
