NAME

6       device_initialize - init device structure.
7

SYNOPSIS

9       void device_initialize(struct device * dev);
10

ARGUMENTS

12       dev
13           device.

DESCRIPTION

16       This prepares the device for use by other layers by initializing its
17       fields. It is the first half of device_register, if called by that
18       function, though it can also be called separately, so one may use dev's
19       fields. In particular, get_device/put_device may be used for reference
20       counting of dev after calling this function.
21
22       All fields in dev must be initialized by the caller to 0, except for
23       those explicitly set to some other value. The simplest approach is to
24       use kzalloc to allocate the structure containing dev.
25

NOTE

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