RTW_DPK_GAIN_CHECK,
The eFuse definitions in the rtw88 are using structs to describe the eFuse contents. Add the packed attribute to all structs used for the eFuse description so the compiler doesn't add gaps or re-order attributes. Also split the res2 eFuse field (which for some reason has parts of it's data in two separate u8 fields) to avoid the following warning, now that their surrounding struct has the packed attribute: note: offset of packed bit-field 'res2' has changed in GCC 4.4 Fixes: e3037485c68e ("rtw88: new Realtek 802.11ac driver") Fixes: ab0a031ecf29 ("rtw88: 8723d: Add read_efuse to recognize efuse info from map") Fixes: 769a29ce2af4 ("rtw88: 8821c: add basic functions") Fixes: 87caeef032fc ("wifi: rtw88: Add rtw8723du chipset support") Fixes: aff5ffd718de ("wifi: rtw88: Add rtw8821cu chipset support") Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- drivers/net/wireless/realtek/rtw88/main.h | 6 +++--- drivers/net/wireless/realtek/rtw88/rtw8723d.h | 6 +++--- drivers/net/wireless/realtek/rtw88/rtw8821c.h | 9 +++++---- drivers/net/wireless/realtek/rtw88/rtw8822b.h | 9 +++++---- drivers/net/wireless/realtek/rtw88/rtw8822c.h | 9 +++++---- 5 files changed, 21 insertions(+), 18 deletions(-)
