I have to say, this is a major fail for what of_match_ptr() intended to do.
commit 3a1e362e3f3cd571b3974b8d44b8e358ec7a098c
Author: Ben Dooks <[email protected]>
Date: Wed Aug 3 10:11:42 2011 +0100
OF: Add of_match_ptr() macro
Add a macro of_match_ptr() that allows the .of_match_table
entry in the driver structures to be assigned without having
an #ifdef xxx NULL for the case that OF is not enabled
Signed-off-by: Ben Dooks <[email protected]>

Should we also depend on CONFIG_OF?

Few other drivers threw similar warnings and the suggestion was to
remove of_match_ptr(). Anyway both approaches look fine.

I don't disagree with this change, I'm just saying that as a next step
we may block this driver from even being compiled if CONFIG_OF=n.

As this looks like a fix, could you please post a new revision of the
patch including into the commit message a proper 'Fixes' tag?
Thanks!
