If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d5cd5019b563dba5b8213fdf8c0137cea643f301 Author: Bitterblue Smith <rtl8821cerfe2@xxxxxxxxx> Date: Thu Dec 1 16:13:57 2022 +0200 wifi: rtl8xxxu: Add __packed to struct rtl8723bu_c2h [ Upstream commit dd469a754afdb782ba3033cee102147493dc39f4 ] This struct is used to access a sequence of bytes received from the wifi chip. It must not have any padding bytes between the members. This doesn't change anything on my system, possibly because currently none of the members need more than byte alignment.
