Subject: [PATCH 1/3] setup: drop return value from `read_repository_format()`
Date: Tue, 18 Dec 2018 08:25:26 +0100	[thread overview]
Message-ID: <20181218072528.3870492-2-martin.agren@gmail.com> (raw)
In-Reply-To: <20181218072528.3870492-1-martin.agren@gmail.com>

No-one looks at the return value, so we might as well drop it. It's
still available as `format->version`.

In v1 of what became commit 2cc7c2c737 ("setup: refactor repo format
reading and verification", 2016-03-11), this function actually had
return type "void", but that was changed in v2. Almost three years
later, no-one has used this return value.

Signed-off-by: Martin Ågren <martin.agren@gmail.com>

 I only discovered the full history after writing the patch. Had I known
 it from the beginning, maybe I'd have just skipped this step, but I was
 sufficiently disturbed by the redundant and unused return value that I
 dropped it before working on the actual meat of this series.
