.SH "NAME"
device_initialize \- init device structure\&.
.SH "SYNOPSIS"
.HP \w'void\ device_initialize('u
.BI "void device_initialize(struct\ device\ *\ " "dev" ");"
.SH "ARGUMENTS"
.PP
\fIdev\fR
.RS 4
device\&.
.RE
.SH "DESCRIPTION"
.PP
This prepares the device for use by other layers by initializing its fields\&. It is the first half of
\fBdevice_register\fR, if called by that function, though it can also be called separately, so one may use
\fIdev\fR\*(Aqs fields\&. In particular,
\fBget_device\fR/\fBput_device\fR
may be used for reference counting of
\fIdev\fR
after calling this function\&.
.PP
All fields in
\fIdev\fR
must be initialized by the caller to 0, except for those explicitly set to some other value\&. The simplest approach is to use
\fBkzalloc\fR
to allocate the structure containing
\fIdev\fR\&.
.SH "NOTE"
.PP
Use
\fBput_device\fR
to give up your reference instead of freeing
\fIdev\fR
directly once you have called this function\&.
