device_initialize — init device structure.
void device_initialize ( | struct device * dev); |
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.
Use put_device to give up your reference instead of freeing
dev directly once you have called this function.
