The value there is limited to 16-bit one, so we don't really need to have a full 32-bit storage for it. Together with followed boolean the structure will be smaller. `pahole` difference before and after: - /* size: 12, cachelines: 1, members: 3 */ - /* padding: 3 */ + /* size: 8, cachelines: 1, members: 3 */ + /* padding: 1 */ Signed-off-by: Andy Shevchenko --- include/linux/gpio/consumer.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/gpio/consumer.h b/include/linux/gpio/consumer.h index 45b651c05b9c..899179972bec 100644 --- a/include/linux/gpio/consumer.h +++ b/include/linux/gpio/consumer.h @@ -587,7 +587,7 @@ struct gpio_desc *devm_fwnode_gpiod_get(struct device *dev, struct acpi_gpio_params { unsigned int crs_entry_index; - unsigned int line_index; + unsigned short line_index; bool active_low; };
