I am fine with them. They also save one error msg from devm_ioremap_resource() in case of platform_get_resource() failure. Best regards, Krzysztof

Use devm_platform_ioremap_resource() helper which makes code a bit cleaner. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> --- drivers/memory/tegra/tegra20-emc.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
