Use the existing GPIO_LOOKUP_IDX() helper macro instead, to relax a dependency on the gpiod_lookup structure's member names. Signed-off-by: Geert Uytterhoeven Cc: Lee Jones Acked-by: Lee Jones --- While this patch is a dependency for "[PATCH v6 4/8] gpiolib: Add support for GPIO lookup by line name", it can be applied independently. But an Acked-by would be nice, too.
