I found it easy to convert it also into the following small script variant for the semantic patch language (Coccinelle software). @adjustment@ expression e, x; @@ +of_node_put(e); if (...) { <+... when != e = x - of_node_put(e); ...+> } -of_node_put(e); 58 patches were accordingly generated for source files of the software “Linux next-20240913”. How would we like to tackle remaining update candidates according to similar transformation patterns? Regards, Markus

Drop OF node reference immediately after using it in syscon_node_to_regmap(), which is both simpler and typical/expected code pattern. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- drivers/pmdomain/rockchip/pm-domains.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
