-Subject: [PATCH] spi/mmc_spi: mmc_spi adaptations for SPI bus locking API
-
-Modification of the mmc_spi driver to use the SPI bus locking API.
-With this, the mmc_spi driver can be used together with other SPI
-devices on the same SPI bus. The exclusive access to the SPI bus is
-now managed in the SPI layer. The counting of chip selects in the probe
-function is no longer needed.
