Subject: [PATCH 1/4] sunxi: gpio: Return void from setter functions
Date: Wed, 20 Oct 2021 23:52:54 -0500	[thread overview]
Message-ID: <20211021045258.30757-2-samuel@sholland.org> (raw)
In-Reply-To: <20211021045258.30757-1-samuel@sholland.org>

The return values of these functions are always zero, and they are
never checked. Since they are not needed, remove them.
