Hmm, somehow I didn't receive the direct mail last time to my Linaro account
(alias of kernel.org). I do see the message being posted to LKML though.

That was an issue on my side.

Sigh, I missed adding it on this one. It should be:

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

As this driver only does DT based matching, of_match_device() will never
return NULL if we've gotten to probe(). Therefore, the NULL check and
error return for it can be dropped.

Will fix and repost.
