Subject: rtw88: mark rtw_fw_hdr __packed
X-Git-Tag: v5.5-rc1~174^2~213^2~27
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=89dca86d29b46f2a5f38ea6476cfd441bd205d25;p=thirdparty%2Fkernel%2Flinux.git

rtw88: mark rtw_fw_hdr __packed

The use of u8 and __le16 in this struct assumes that it's going to be
packed to byte alignment. C doesn't guarantee that, so we should mark
this __packed.
