Subject: [PATCH 27/29] brcmfmac: Remove {r,w}_sdreg32
Date: Mon, 17 Jul 2017 17:16:35 +0100 [thread overview]
Message-ID: <20170717161637.4652-28-ian@mnementh.co.uk> (raw)
In-Reply-To: <20170717161637.4652-1-ian@mnementh.co.uk>
Remove yet another IO function from the code and replace with one
that already exists.
