'default' on a choice refers to the symbol selected by default, not to the choice mode, so 'default n' is meaningless.
No functional changes. Optional choices implicitly default to n mode (and there is no way to make them default to another mode).
Discovered in Kconfiglib (https://github.com/ulfalizer/Kconfiglib), which prints the following warning:
warning: the default selection n (undefined) of <choice> (defined at drivers/usb/ulpi/Kconfig:3) is not contained in the choice
I've added a corresponding warning to the C tools too, which is currently in linux-next: https://patchwork.kernel.org/patch/9983667/
