SPI_ALLOC_DEVICE(9)               Serial Peripheral Interface (S              SPI_ALLOC_DEVICE(9)



NAME
       spi_alloc_device - Allocate a new SPI device

SYNOPSIS
       struct spi_device * spi_alloc_device(struct spi_master * master);

ARGUMENTS
       master
           Controller to which device is connected

CONTEXT
       can sleep

DESCRIPTION
       Allows a driver to allocate and initialize a spi_device without registering it
       immediately. This allows a driver to directly fill the spi_device with device parameters
       before calling spi_add_device on it.

       Caller is responsible to call spi_add_device on the returned spi_device structure to add
       it to the SPI master. If the caller needs to discard the spi_device without adding it,
       then it should call spi_dev_put on it.

RETURN
       a pointer to the new device, or NULL.
