Then please fix the patch and do it in a way

label = "green:user1"; /* ds2 */

ds2 reflects name on schematics.

in ds4 case default trigger is changes to mmc1. It suggests sd/emmc but
on ultra96 it is sd slot and wifi on second slot.

ds5 - linux,default-trigger = "none"; looks weird. None trigger should
be simply ensured by removing that line.
