wifi: mwl8k: Avoid -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. There is currently an object (`header`), at the beginning of multiple structures, that contains a flexible structure (`struct mwl8k_cmd_pkt`), for example: struct mwl8k_cmd_get_hw_spec_sta { struct mwl8k_cmd_pkt header; ... __le32 num_tx_desc_per_queue; __le32 total_rxd; } __packed; So, in order to avoid ending up with flexible-array members in the middle of multiple other structs, we use the `__struct_group()` helper to separate the flexible array from the rest of the members in the flexible structure: struct mwl8k_cmd_pkt { __struct_group(mwl8k_cmd_pkt_hdr, hdr, __packed, ... the rest of the members ); char payload[]; } __packed; With the change described above, we now declare objects of the type of the tagged struct, in this case `struct mwl8k_cmd_pkt_hdr`, without embedding flexible arrays in the middle of another struct: struct mwl8k_cmd_get_hw_spec_sta { struct mwl8k_cmd_pkt_hdr header; ... __le32 num_tx_desc_per_queue; __le32 total_rxd; } __packed; Also, update the type of a couple of variables and function parameters from `struct mwl8k_cmd_pkt` to `struct mwl8k_cmd_pkt_hdr`. So, with these changes, fix 33 of the following warnings[1]: drivers/net/wireless/marvell/mwl8k.c:2353:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: https://gist.github.com/GustavoARSilva/7a841a92c0f24e5efdb30ce02b601eb8 [1] Link: https://github.com/KSPP/linux/issues/202 Signed-off-by: Gustavo A.
