Subject: [PATCH 16/29] brcmfmac: Cleanup offsetof()
Date: Mon, 17 Jul 2017 17:16:24 +0100	[thread overview]
Message-ID: <20170717161637.4652-17-ian@mnementh.co.uk> (raw)
In-Reply-To: <20170717161637.4652-1-ian@mnementh.co.uk>

Create a macro to make the code a bit more readable, whilst we're stuck
with using struct element offsets as register offsets.
