spi_alloc_device — Allocate a new SPI device
struct spi_device * spi_alloc_device ( | struct spi_master * master); |
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.
Returns a pointer to the new device, or NULL.
