.SH "NAME"
spi_alloc_device \- Allocate a new SPI device
.SH "SYNOPSIS"
.HP \w'struct\ spi_device\ *\ spi_alloc_device('u
.BI "struct spi_device * spi_alloc_device(struct\ spi_master\ *\ " "master" ");"
.SH "ARGUMENTS"
.PP
\fImaster\fR
.RS 4
Controller to which device is connected
.RE
.SH "CONTEXT"
.PP
can sleep
.SH "DESCRIPTION"
.PP
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
\fBspi_add_device\fR
on it\&.
.PP
Caller is responsible to call
\fBspi_add_device\fR
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
\fBspi_dev_put\fR
on it\&.
.PP
Returns a pointer to the new device, or NULL\&.
