Subject: [U-Boot] [PATCH] usb: ulpi: kconfig: Remove meaningless choice default
Date: Tue, 30 Jan 2018 14:07:05 +0100	[thread overview]
Message-ID: <20180130130705.6647-1-ulfalizer@gmail.com> (raw)

'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/
