Rahul Rameshbabu	8bcf314b92	HID: nvidia-shield: Pack inner/related declarations in HOSTCMD reports ... Match alignment information in composite type declarations used by packed HOSTCMD report structures. Compiler packing attribute is not recursive for inner declarations. Mismatched alignment information can cause undefined behavior in code generated for accessing composite type members. struct pointers passed to thunderstrike_parse_board_info_payload and thunderstrike_parse_haptics_payload are an example of this being potentially problematic since alignment information from the packed HOSTCMD report is lost.
