Subject: [PATCH] Specify return value where named return value is used

After [v0.9.0](https://github.com/mvdan/gofumpt/releases/tag/v0.9.0),
gofumpt prohibits "naked return" for the sake of clarity. This makes
more readable when "named return value" is used.
For more infomation for "prohibition of naked return":
https://github.com/mvdan/gofumpt/issues/285.
