The modalias sysfs attr is lacking a newline for DT aliases on platform
devices. The macio and ibmebus correctly add the newline, but open code it.
Introduce a new function, of_device_modalias(), that fills the buffer with
the modalias including the newline and update users of the old
of_device_get_modalias function.

of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.
This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Now that the of_node pointer is part of struct device,
of_device_get_modalias could be used on any struct device
that has the device node pointer set. This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated. This patch
makes all readers of these elements use device.of_node instead.
(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

Create /sys/bus/of_platform/devices/*/modalias file to allow autoloading
of modules. Modalias files are already present for many other bus types.
This adds also a newline to the devspec files.
Also create a devspec file for mac-io devices. They were created as a
side effect. Use correct buffer size for mac-io modalias buffer.
Tested on iBook1 and Efika.

There is now a common function to generate the modalias string,
so use it. We just need to add the \n at the end.

Currently the buf pointer is advanced too far during each iteration.

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

This adds sysfs nodes that the hotplug userspace can use to load the
appropriate modules.
In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied. Those patches are
available at:
ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/
Changes: The previous versions were built on 2.6.12. 2.6.13-rcX introduced
a device_attribute parameter to the show functions. Since that
parameter was treated as the output buffer, memory corruption would
result, causing Oopsen very quickly.
