NAME¶
spi_alloc_device - Allocate a new SPI deviceSYNOPSIS¶
struct spi_device *
spi_alloc_device(struct spi_master * master);
ARGUMENTS¶
masterController to which device is connected
CONTEXT¶
can sleepDESCRIPTION¶
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.COPYRIGHT¶
