Fixing of_match_ptr =

diff --git a/include/linux/of.h b/include/linux/of.h
index a0bedd038a05..d980bccffda0 100644
--- a/include/linux/of.h
+++ b/include/linux/of.h
@@ -890,7 +890,7 @@ static inline const void *of_device_get_match_data(const struct device *dev)
 	return NULL;
 }
 
-#define of_match_ptr(_ptr)	NULL
+#define of_match_ptr(_ptr)	(0 ? (_ptr) : NULL)
 #define of_match_node(_matches, _node)	NULL
 #endif /* CONFIG_OF */
 
?

Assuming this helps, I agree this would be the better fix.

Best regards
Uwe
