From 718eae277e62a26e5862eb72a830b5e0fe37b04a Mon Sep 17 00:00:00 2001 From: Mao Wenan Date: Mon, 9 Dec 2019 21:08:45 +0800 Subject: [PATCH] NFC: port100: Convert cpu_to_le16(le16_to_cpu(E1) + E2) to use le16_add_cpu(). Convert cpu_to_le16(le16_to_cpu(frame->datalen) + len) to use le16_add_cpu(), which is more concise and does the same thing. Reported-by: Hulk Robot Signed-off-by: Mao Wenan Signed-off-by: David S.
