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
