mac80211: Add attribute aligned(2) to struct 'action'
During refactor in commit 9e478066eae4 ("mac80211: fix MU-MIMO follow-MAC mode") a new struct 'action' was declared with packed attribute as: struct { struct ieee80211_hdr_3addr hdr; u8 category; u8 action_code; } __packed action; But since struct 'ieee80211_hdr_3addr' is declared with an aligned keyword as: struct ieee80211_hdr { __le16 frame_control; __le16 duration_id; u8 addr1[ETH_ALEN]; u8 addr2[ETH_ALEN]; u8 addr3[ETH_ALEN]; __le16 seq_ctrl; u8 addr4[ETH_ALEN]; } __packed __aligned(2); Solve the ambiguity of placing aligned structure in a packed one by adding the aligned(2) attribute to struct 'action'. This removes the following warning (W=1): net/mac80211/rx.c:234:2: warning: alignment 1 of 'struct <anonymous>' is less than 2 [-Wpacked-not-aligned] Cc: Johannes Berg <johannes.berg@intel.com> Suggested-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
