From fb1bc2ce3a55bee62e405364512a5b5e53074418 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 4 Feb 2021 17:26:43 +0100 Subject: [PATCH] wl3501: fix alignment constraints struct wl3501_80211_tx_hdr contains a ieee80211_hdr structure, which is required to have at least two byte alignment, and this conflicts with the __packed attribute: wireless/wl3501.h:553:1: warning: alignment 1 of 'struct wl3501_80211_tx_hdr' is less than 2 [-Wpacked-not-aligned] Mark wl3501_80211_tx_hdr itself as having two-byte alignment to ensure the inner structure is properly aligned.
