From b09c1359e4f08bc8369357cf4ec4a08150b47888 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 15 Sep 2023 20:10:03 +0200 Subject: [PATCH] net: hsr: Add __packed to struct hsr_sup_tlv. [ Upstream commit fbd825fcd7dd4c11d4c48c3d0adc248a4a0ce90b ] Struct hsr_sup_tlv describes HW layout and therefore it needs a __packed attribute to ensure the compiler does not add any padding. Due to the size and __packed attribute of the structs that use hsr_sup_tlv it has no functional impact. Add __packed to struct hsr_sup_tlv.
