[PATCH] of: Fix export of of_find_matching_node_and_match()

[PATCH] of: Fix export of of_find_matching_node_and_match()

[Grant Likely]

Commit 50c8af4cf9, "of: introduce for_each_matching_node_and_match()"
renamed of_find_matching_node() to of_find_matching_node_and_match() and
created a new static inline of_find_matching_node() wrapper around the
new name. However, the change neglected to change the EXPORT_SYMBOL()
reference causing build errors for modules.

This patch fixes the EXPORT_SYMBOL() statement. Discovered on a PowerPC
Efika build with the mpc52xx_uart driver being built as a module.

Rob, I've just pushed this out to my devicetree/merge branch. If
you've got any fixes queued up for Linus, then please pull this in
before sending them on to him. Otherwise I'll send Linus a pull req
for this fix this evening. Ether way, please reply to let me know what
you're going to do.

The only item on my todo is this one:

"of: define struct device in of_platform.h if !OF_DEVICE and !OF_ADDRESS"

But I'm not going to get to it today if you want to pick it up.

I don't see that one anywhere. Where did it come from?

Oops. The patch is obviously correct,
Reviewed-by: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

I guess none of the ARM defconfigs enable any module that uses this,
since I have built all of them multiple times recently:-(
