Message-ID: <20200214162425.21071-37-sashal@kernel.org> (raw)
In-Reply-To: <20200214162425.21071-1-sashal@kernel.org>

[ Upstream commit 718eae277e62a26e5862eb72a830b5e0fe37b04a ]
Convert cpu_to_le16(le16_to_cpu(frame->datalen) + len) to
use le16_add_cpu(), which is more concise and does the same thing.
