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.
Returns a pointer to the new device, or NULL.
