The line_index member in the struct acpi_gpio_params replicates what is covered in the ACPI GpioIo() or GpioInt() resource. 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. add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3 (-3) Function old new delta acpi_gpio_property_lookup 417 414 -3 Total: Before=15361, After=15358, chg -0.02% `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 <andriy.shevchenko@linux.intel.com> --- include/linux/gpio/consumer.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
