Subject: [PATCH AUTOSEL 4.19 079/252] NFC: port100: Convert cpu_to_le16(le16_to_cpu(E1) + E2) to use le16_add_cpu().
Date: Fri, 14 Feb 2020 11:08:54 -0500	[thread overview]
Message-ID: <20200214161147.15842-79-sashal@kernel.org> (raw)
In-Reply-To: <20200214161147.15842-1-sashal@kernel.org>

From: Mao Wenan <maowenan@huawei.com>

[ 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.
