Marc Kleine-Budde 8bc5ed70ef can: ems_usb: fix clang's -Wunaligned-access warning ... commit a4cb6e62ea upstream. clang emits a -Wunaligned-access warning on struct __packed ems_cpc_msg. The reason is that the anonymous union msg (not declared as packed) is being packed right after some non naturally aligned variables (3*8 bits + 2*32) inside a packed struct: | struct __packed ems_cpc_msg { | u8 type; /* type of message */ | u8 length; /* length of data within union 'msg' */ | u8 msgid; /* confirmation handle */ | __le32 ts_sec; /* timestamp in seconds */ | __le32 ts_nsec; /* timestamp in nano seconds */ | /* ^ not naturally aligned */ | | union { | /* ^ not declared as packed */ | u8 generic[64]; | struct cpc_can_msg can_msg; | struct cpc_can_params can_params; | struct cpc_confirm confirmation; | struct cpc_overrun overrun; | struct cpc_can_error error; | struct cpc_can_err_counter err_counter; | u8 can_state; | } msg; | }; Starting from LLVM 14, having an unpacked struct nested in a packed struct triggers a warning. c.f. [1]. Fix the warning by marking the anonymous union as packed.
