## Name

device_initialize — init device structure.

## Synopsis

`void device_initialize (` | struct device * dev`)`;

## Arguments

`dev`

  device.

## Description

This prepares the device for use by other layers by initializing its fields. It is the first half of `device_register`, if called by that function, though it can also be called separately, so one may use `dev`'s fields. In particular, `get_device`/`put_device` may be used for reference counting of `dev` after calling this function.

All fields in `dev` must be initialized by the caller to 0, except for those explicitly set to some other value. The simplest approach is to use `kzalloc` to allocate the structure containing `dev`.

## NOTE

Use `put_device` to give up your reference instead of freeing `dev` directly once you have called this function.
